I'm seeing the crash on linux on x86 with just `clang q.cc`. However, on
other platforms one may need cc1 arguments. The important ones seem to be:
$ clang++ -cc1 -triple x86_64-unknown-linux-gnu -emit-obj
 -mconstructor-aliases q.cc
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
Stack dump:
0.      Program arguments: clang++ -cc1 -triple x86_64-unknown-linux-gnu
-emit-obj -mconstructor-aliases q.cc
