/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!type->hasTypeParameter() && "already have an interface type"` added on 2016-12-18 by you in commit fb0f372e :-)

Assertion failure in [`lib/AST/GenericEnvironment.cpp (line 172)`](https://github.com/apple/swift/blob/master/lib/AST/GenericEnvironment.cpp#L172):

```
Assertion `!type->hasTypeParameter() && "already have an interface type"' failed.

When executing: static swift::Type swift::GenericEnvironment::mapTypeOutOfContext(swift::GenericEnvironment *, swift::Type)
```

Assertion context:

a4c1bd6a78 [swiftc (45 vs. 5395)] Add crasher in swift::Expr::propagateLValueAccessKind 
Add test case for crash triggered in `swift::Expr::propagateLValueAccessKind`.

Current number of unresolved compiler crashers: 45 (5395 resolved)

/cc @rudkx - just wanted to let you know that this crasher caused an assertion failure for the assertion `GetType(E)->isAssignableType() && "setting access kind on non-l-value"` added on 2016-12-12 by you in commit 59ce1ff73 :-)

Assertion failure in [`lib/AST/Expr.cpp (line 238)`](https://github.com/apple/swift/blob/master/lib/AST/Expr.cpp#L238):

```
Assertion `GetType(E)->isAssignableType() && "setting access kind on non-l-value"' failed.

When executing: void swift::Expr::propagateLValueAccessKind(swift::AccessKind, llvm::function_ref<Type (Expr *)>, bool)::PropagateAccessKind::visit(swift::Expr *, swift::AccessKind)
```

Assertion context:

```
    void visit(Expr *E, AccessKind kind) {
      assert((AllowOverwrite || !E->hasLValueAccessKind()) &&
             "l-value access kind has already been set");

      assert(GetType(E)->isAssignableType() &&
             "setting access kind on non-l-value");
      E->setLValueAccessKind(kind);

      // Propagate this to sub-expressions.
      ASTVisitor::visit(E, kind);
    }
```

b4cef31ecc [swiftc (42 vs. 5395)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 42 (5395 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `destOptionals.size() - destExtraOptionals <= srcOptionals.size()` added on 2014-06-21 by you in commit 044ff2f4e :-)

Assertion failure in [`lib/Sema/CSApply.cpp (line 3165)`](https://github.com/apple/swift/blob/master/lib/Sema/CSApply.cpp#L3165):

```
Assertion `destOptionals.size() - destExtraOptionals <= srcOptionals.size()' failed.

When executing: swift::Expr *(anonymous namespace)::ExprRewriter::handleOptionalBindings(swift::ExplicitCastExpr *, swift::Type, (anonymous namespace)::ExprRewriter::OptionalBindingsCastKind)
```

Assertion context:

```
        cs.setType(cast, destValueType);
      }

      // The result type (without the final optional) is a subtype of
      // the operand type, so it will never have a higher depth.
      assert(destOptionals.size() - destExtraOptionals <= srcOptionals.size());

      // The outermost N levels of optionals on the operand must all
      // be present or the cast fails.  The innermost M levels of
      // optionals on the operand are reflected in the requested
      // destination type, so we should map these nils into the result.
```

b83ed1d5e0 [swiftc (44 vs. 5390)] Add crasher in swift::constraints::ConstraintGraph::lookupNode(...) 
Add test case for crash triggered in `swift::constraints::ConstraintGraph::lookupNode(...)`.

Current number of unresolved compiler crashers: 44 (5390 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `TypeVariables[impl.getGraphIndex()] == typeVar && "Type variable mismatch"` added on 2013-12-09 by you in commit 11794095 :-)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 52)`](https://github.com/apple/swift/blob/master/lib/Sema/ConstraintGraph.cpp#L52):

```
Assertion `TypeVariables[impl.getGraphIndex()] == typeVar && "Type variable mismatch"' failed.

When executing: std::pair<ConstraintGraphNode &, unsigned int> swift::constraints::ConstraintGraph::lookupNode(swift::TypeVariableType *)
```

Assertion context:

```
  // Check whether we've already created a node for this type variable.
  auto &impl = typeVar->getImpl();
  if (auto nodePtr = impl.getGraphNode()) {
    assert(impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index");
    assert(TypeVariables[impl.getGraphIndex()] == typeVar &&
           "Type variable mismatch");
    return { *nodePtr, impl.getGraphIndex() };
  }

  // Allocate the new node.
  auto nodePtr = new ConstraintGraphNode(typeVar);
```

8d4afc1e9d [swiftc (37 vs. 5390)] Add crasher in swift::ASTVisitor 
Add test case for crash triggered in `swift::ASTVisitor`.

Current number of unresolved compiler crashers: 37 (5390 resolved)

/cc @rjmccall - just wanted to let you know that this crasher caused an assertion failure for the assertion `args.size() > fnRef.getNumArgumentsForFullApply() && "partial application was throwing?"` added on 2015-05-13 by you in commit 7a5ffedd :-)

Assertion failure in [`lib/Sema/TypeCheckError.cpp (line 427)`](https://github.com/apple/swift/blob/master/lib/Sema/TypeCheckError.cpp#L427):

```
Assertion `args.size() > fnRef.getNumArgumentsForFullApply() && "partial application was throwing?"' failed.

```

Assertion context:

```
    // If we're applying more arguments than the natural argument
    // count, then this is a call to the opaque value returned from
    // the function.

Add test case for crash triggered in `swift::SequenceExpr::create`.

Current number of unresolved compiler crashers: 33 (5390 resolved)

/cc @nkcsgexi - just wanted to let you know that this crasher caused an assertion failure for the assertion `elements.size() & 1 && "even number of elements in sequence"` added on 2015-12-09 by you in commit 2f670a813 :-)

Assertion failure in [`lib/AST/Expr.cpp (line 1320)`](https://github.com/apple/swift/blob/master/lib/AST/Expr.cpp#L1320):

```
Assertion `elements.size() & 1 && "even number of elements in sequence"' failed.

When executing: static swift::SequenceExpr *swift::SequenceExpr::create(swift::ASTContext &, ArrayRef<swift::Expr *>)

Assertion context:

```

  return false;
