Comment (by kencu):
OK, so the crash is reproducible. Steps to reproduce:
1. install llvm-devel (comes with assertions on)
2. install cctools +llvmdev
3. select clang-devel using `sudo port select clang clang-devel`
4. try to build gcc9 `sudo port -v destroot gcc9 configure.compiler
=macports-clang
and you get mouse's exact error, more or less, in clang trunk:
{{{
