Add test case for crash triggered in `swift::MetatypeType::get`. Current number of unresolved compiler crashers: 38 (5451 resolved) /cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `CurrentConstraintSolverArena && "No constraint solver active?"` added on 2012-11-14 by you in commit2183b57fa:-) Assertion failure in [`lib/AST/ASTContext.cpp (line 358)`](c2775070e2/lib/AST/ASTContext.cpp (L358)): ``` Assertion `CurrentConstraintSolverArena && "No constraint solver active?"' failed. When executing: swift::ASTContext::Implementation::Arena &swift::ASTContext::Implementation::getArena(swift::AllocationArena) ``` Assertion context: ```c++ switch (arena) { case AllocationArena::Permanent: return Permanent; case AllocationArena::ConstraintSolver: assert(CurrentConstraintSolverArena && "No constraint solver active?"); return *CurrentConstraintSolverArena; } llvm_unreachable("bad AllocationArena"); } ``` Stack trace: ``` 0 0x00000000038a4038 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x38a4038) 1 0x00000000038a4776 SignalHandler(int) (/path/to/swift/bin/swift+0x38a4776) 2 0x00007f0e9d8713e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007f0e9c1d7428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007f0e9c1d902a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007f0e9c1cfbd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007f0e9c1cfc82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x000000000133591a swift::MetatypeType::get(swift::Type, llvm::Optional<swift::MetatypeRepresentation>, swift::ASTContext const&) (/path/to/swift/bin/swift+0x133591a) 8 0x0000000001428b83 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x1428b83) 9 0x000000000127d5b0 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x127d5b0) 10 0x000000000127da1a (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x127da1a) 11 0x00000000013ab80e swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13ab80e) 12 0x00000000013aa5db swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13aa5db) 13 0x000000000127ea30 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x127ea30) 14 0x00000000013aaad4 (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13aaad4) 15 0x00000000013adc78 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13adc78) 16 0x00000000013aa65e swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13aa65e) 17 0x000000000127c7b1 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x127c7b1) 18 0x00000000011b301b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11b301b) 19 0x00000000011b37f5 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11b37f5) 20 0x0000000000f09576 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf09576) 21 0x00000000004a4aa6 swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) (/path/to/swift/bin/swift+0x4a4aa6) 22 0x0000000000463c07 main (/path/to/swift/bin/swift+0x463c07) 23 0x00007f0e9c1c2830 __libc_start_main /build/glibc-Qz8a69/glibc-2.23/csu/../csu/libc-start.c:325:0 24 0x00000000004612a9 _start (/path/to/swift/bin/swift+0x4612a9) ```
