Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 51 (5433 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)`](5fe6f33ae5/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 0x00000000038a11c8 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x38a11c8) 1 0x00000000038a1906 SignalHandler(int) (/path/to/swift/bin/swift+0x38a1906) 2 0x00007ff8833b73e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007ff881d1d428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007ff881d1f02a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007ff881d15bd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007ff881d15c82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x0000000001426e48 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x1426e48) 8 0x000000000127e1e0 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x127e1e0) 9 0x000000000127e64a (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x127e64a) 10 0x00000000013a99fe swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13a99fe) 11 0x00000000013a87fb swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13a87fb) 12 0x000000000127f660 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x127f660) 13 0x00000000013a8cbe (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13a8cbe) 14 0x00000000013ae264 (anonymous namespace)::Traversal::visitNominalTypeDecl(swift::NominalTypeDecl*) (/path/to/swift/bin/swift+0x13ae264) 15 0x00000000013a8d0b (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13a8d0b) 16 0x00000000013abe68 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13abe68) 17 0x00000000013a887e swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13a887e) 18 0x000000000127d3e1 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x127d3e1) 19 0x00000000011b3a0b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11b3a0b) 20 0x00000000011b41e5 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11b41e5) 21 0x0000000000f0ba26 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf0ba26) 22 0x00000000004a4706 swift::performFrontend(llvm::ArrayRef<char const*>, char const*, void*, swift::FrontendObserver*) (/path/to/swift/bin/swift+0x4a4706) 23 0x00000000004639c7 main (/path/to/swift/bin/swift+0x4639c7) 24 0x00007ff881d08830 __libc_start_main /build/glibc-Qz8a69/glibc-2.23/csu/../csu/libc-start.c:325:0 25 0x0000000000461069 _start (/path/to/swift/bin/swift+0x461069) ```
