I am the maintainer of GNU-family Objective-C runtime support in clang 
and of the GNUstep runtime.  Unless you assign these bugs to me in the 
LLVM Bugzilla, I am unlikely to see them.  I am far more likely to see 
and be able to fix them if I see a post in this list, because it's much 
lower traffic.

If you add -### to the end of your clang invocation, it will show the 
clang -cc1 invocation that runs the actual compiler.  If you then run 
that in a debugger, you should be able to get a useful back trace.  Note 
that clang-7.0.1 is quite old.  There were quite a few fixes in the 7-8 
timeframe, so trying with clang-10 would also be helpful.
