clang crash log

When I compiler firefox gecko48 with clang, I encounter the clang crash when
compiling gecko/js/src/ctypes/CTypes.cpp. 

Looks like clang is crashed while compiling this function.

js::ctypes::GetDeflatedUTF8StringLength()

Not quite sure how to debug further or how to find exactly line of code leads
to clang crash.
