I just rebuilt clang today (r194205) to verify that bug #17724 is indeed fixed,
but now clang asserts somewhere else. (May or may not be related to #17724.
I'm building again with -Wno-consumed to see.)
Assertion failed: (Val && "isa<> used on a null pointer"), function doit, file
/Users/builder/llvm/llvm/include/llvm/Support/Casting.h, line 97.
