Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 45 (5451 resolved) /cc @lattner - just wanted to let you know that this crasher caused an assertion failure for the assertion `Result && "Case not implemented!"` added on 2011-03-22 by you in commitfd2bf74f:-) Assertion failure in [`lib/AST/Type.cpp (line 1299)`](72f7beead6/lib/AST/Type.cpp (L1299)): ``` Assertion `Result && "Case not implemented!"' failed. When executing: swift::CanType swift::TypeBase::getCanonicalType() ``` Assertion context: ```c++ SmallVector<Type, 4> CanGenericArgs; for (Type Arg : BGT->getGenericArgs()) CanGenericArgs.push_back(Arg->getCanonicalType()); Result = BoundGenericType::get(BGT->getDecl(), parentTy, CanGenericArgs); break; } } // Cache the canonical type for future queries. assert(Result && "Case not implemented!"); ``` Stack trace: ``` 0 0x00000000038db698 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x38db698) 1 0x00000000038dbdd6 SignalHandler(int) (/path/to/swift/bin/swift+0x38dbdd6) 2 0x00007f1d1808b3e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007f1d169f1428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007f1d169f302a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007f1d169e9bd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007f1d169e9c82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x0000000001431478 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x1431478) 8 0x0000000001283aa0 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x1283aa0) 9 0x0000000001283f0a (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x1283f0a) 10 0x00000000013b350e swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13b350e) 11 0x00000000013b22db swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13b22db) 12 0x0000000001284f20 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x1284f20) 13 0x00000000013b27d4 (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13b27d4) 14 0x00000000013b5978 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13b5978) 15 0x00000000013b235e swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13b235e) 16 0x0000000001282ca1 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x1282ca1) 17 0x00000000011b837b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11b837b) 18 0x00000000011b8b55 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11b8b55) 19 0x0000000000f0ccf6 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf0ccf6) 20 0x00000000004a51d6 swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) (/path/to/swift/bin/swift+0x4a51d6) 21 0x0000000000464337 main (/path/to/swift/bin/swift+0x464337) 22 0x00007f1d169dc830 __libc_start_main /build/glibc-Qz8a69/glibc-2.23/csu/../csu/libc-start.c:325:0 23 0x00000000004619d9 _start (/path/to/swift/bin/swift+0x4619d9) ```
