Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 39 (5431 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)`](9cc9ae03f6/lib/AST/Type.cpp (L1299)): ``` Assertion `Result && "Case not implemented!"' failed. When executing: swift::CanType swift::TypeBase::getCanonicalType() ``` Assertion context: ```c++ } } // Cache the canonical type for future queries. assert(Result && "Case not implemented!"); CanonicalType = Result; return CanType(Result); } ``` Stack trace: ``` 0 0x0000000003897f68 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x3897f68) 1 0x00000000038986a6 SignalHandler(int) (/path/to/swift/bin/swift+0x38986a6) 2 0x00007f4e689fb3e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007f4e67361428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007f4e6736302a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007f4e67359bd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007f4e67359c82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x0000000001422328 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x1422328) 8 0x0000000001279f50 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x1279f50) 9 0x000000000127a3ba (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x127a3ba) 10 0x00000000013a637e swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13a637e) 11 0x00000000013a517b swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13a517b) 12 0x000000000127b3d0 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x127b3d0) 13 0x00000000013a563e (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13a563e) 14 0x00000000013a87f8 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13a87f8) 15 0x00000000013a51fe swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13a51fe) 16 0x0000000001279130 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x1279130) 17 0x00000000011af53b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11af53b) 18 0x00000000011afd15 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11afd15) 19 0x0000000000f0b446 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf0b446) 20 0x00000000004a4606 swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) (/path/to/swift/bin/swift+0x4a4606) 21 0x00000000004638c7 main (/path/to/swift/bin/swift+0x4638c7) 22 0x00007f4e6734c830 __libc_start_main /build/glibc-Qz8a69/glibc-2.23/csu/../csu/libc-start.c:325:0 23 0x0000000000460f69 _start (/path/to/swift/bin/swift+0x460f69) ```
