Current number of unresolved compiler crashers: 57 (5396 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 commit fd2bf74 :-) Assertion failure in [`lib/AST/Type.cpp (line 1292)`](https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L1292): ``` Assertion `Result && "Case not implemented!"' failed. When executing: swift::CanType swift::TypeBase::getCanonicalType() ``` Assertion context: ``` } } // Cache the canonical type for future queries. assert(Result && "Case not implemented!"); CanonicalType = Result; return CanType(Result); } ``` Stack trace: ``` 0 0x000000000351a038 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x351a038) 1 0x000000000351a776
