Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`. Current number of unresolved compiler crashers: 52 (5454 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 1304)`](ee4100ca8a/lib/AST/Type.cpp (L1304)): ``` Assertion `Result && "Case not implemented!"' failed. When executing: swift::CanType swift::TypeBase::getCanonicalType() ``` Assertion context: ```c++ break; } } // Cache the canonical type for future queries. assert(Result && "Case not implemented!"); CanonicalType = Result; return CanType(Result); } ``` Stack trace: ``` 0 0x00000000038f7ef8 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x38f7ef8) 1 0x00000000038f8636 SignalHandler(int) (/path/to/swift/bin/swift+0x38f8636) 2 0x00007fc3d90803e0 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x113e0) 3 0x00007fc3d79e6428 gsignal /build/glibc-Qz8a69/glibc-2.23/signal/../sysdeps/unix/sysv/linux/raise.c:54:0 4 0x00007fc3d79e802a abort /build/glibc-Qz8a69/glibc-2.23/stdlib/abort.c:91:0 5 0x00007fc3d79debd7 __assert_fail_base /build/glibc-Qz8a69/glibc-2.23/assert/assert.c:92:0 6 0x00007fc3d79dec82 (/lib/x86_64-linux-gnu/libc.so.6+0x2dc82) 7 0x000000000144c408 swift::TypeBase::getCanonicalType() (/path/to/swift/bin/swift+0x144c408) 8 0x00000000012995c0 (anonymous namespace)::FindCapturedVars::checkType(swift::Type, swift::SourceLoc) (/path/to/swift/bin/swift+0x12995c0) 9 0x0000000001299a2a (anonymous namespace)::FindCapturedVars::walkToExprPre(swift::Expr*) (/path/to/swift/bin/swift+0x1299a2a) 10 0x00000000013baf7e swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Expr*) (/path/to/swift/bin/swift+0x13baf7e) 11 0x00000000013b9d4b swift::Expr::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13b9d4b) 12 0x000000000129aa40 (anonymous namespace)::FindCapturedVars::walkToDeclPre(swift::Decl*) (/path/to/swift/bin/swift+0x129aa40) 13 0x00000000013ba244 (anonymous namespace)::Traversal::doIt(swift::Decl*) (/path/to/swift/bin/swift+0x13ba244) 14 0x00000000013bd478 swift::ASTVisitor<(anonymous namespace)::Traversal, swift::Expr*, swift::Stmt*, bool, swift::Pattern*, bool, void>::visit(swift::Stmt*) (/path/to/swift/bin/swift+0x13bd478) 15 0x00000000013b9dce swift::Stmt::walk(swift::ASTWalker&) (/path/to/swift/bin/swift+0x13b9dce) 16 0x00000000012987c1 swift::TypeChecker::computeCaptures(swift::AnyFunctionRef) (/path/to/swift/bin/swift+0x12987c1) 17 0x00000000011cd98b typeCheckFunctionsAndExternalDecls(swift::TypeChecker&) (/path/to/swift/bin/swift+0x11cd98b) 18 0x00000000011ce1d8 swift::performTypeChecking(swift::SourceFile&, swift::TopLevelContext&, swift::OptionSet<swift::TypeCheckingFlags, unsigned int>, unsigned int, unsigned int) (/path/to/swift/bin/swift+0x11ce1d8) 19 0x0000000000f220b6 swift::CompilerInstance::performSema() (/path/to/swift/bin/swift+0xf220b6) 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 0x00007fc3d79d1830 __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) ```
