Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 40 (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)`](efc870a2d9/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 0x000000000389f498 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x389f498) 1 0x000000000389fbd6 SignalHandler(int) (/path/to/swift/bin/swift+0x389fbd6) 2 0x00007f900cfcd3e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007f900b933428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007f900b93502a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007f900b92bbd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007f900b92bc82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x00000000014292c8 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x14292c8) 8 0x000000000127d8c0 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x127d8c0) 9 0x000000000127dd2a (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x127dd2a) 10 0x00000000013abb1e swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13abb1e) 11 0x00000000013aa8eb swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13aa8eb) 12 0x000000000127ed40 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x127ed40) 13 0x00000000013aade4 (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13aade4) 14 0x00000000013adf88 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13adf88) 15 0x00000000013aa96e swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13aa96e) 16 0x000000000127cac1 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x127cac1) 17 0x00000000011b312b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11b312b) 18 0x00000000011b3905 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11b3905) 19 0x0000000000f09586 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf09586) 20 0x00000000004a4aa6 swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) (/path/to/swift/bin/swift+0x4a4aa6) 21 0x0000000000463c07 main (/path/to/swift/bin/swift+0x463c07) 22 0x00007f900b91e830 __libc_start_main /build/glibc-Qz8a69/glibc-2.23/csu/../csu/libc-start.c:325:0 23 0x00000000004612a9 _start (/path/to/swift/bin/swift+0x4612a9) ```
