Add test case for crash triggered in `swift::TypeChecker::substMemberTypeWithBase`. Current number of unresolved compiler crashers: 49 (5582 resolved) /cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `isa<ClassDecl>(nominalDecl) && "expected a class here"` added on 2017-04-07 by you in commit473faf1e:-) Assertion failure in [`lib/AST/Type.cpp (line 3230)`](e1e759c758/lib/AST/Type.cpp (L3230)): ``` Assertion `isa<ClassDecl>(nominalDecl) && "expected a class here"' failed. When executing: swift::Type swift::TypeBase::getSuperclassForDecl(const swift::ClassDecl *) ``` Assertion context: ```c++ "expected a class, archetype or existential"); t = t->getSuperclass(); assert(t && "archetype or existential is not class constrained"); continue; } assert(isa<ClassDecl>(nominalDecl) && "expected a class here"); if (nominalDecl == baseClass) return t; t = t->getSuperclass(); ``` Stack trace: ``` 0 0x0000000003ae8f28 llvm::sys::PrintStackTrace(llvm::raw_ostream&) (/path/to/swift/bin/swift+0x3ae8f28) 1 0x0000000003ae9666 SignalHandler(int)
