GCC 9 ICE (internal compiler error) when using coverage

Question

Using EDG frontend compiler to generate CPP code started to crash on GCC 9/10/11, used to work on GCC 6.3.0.

   during IPA pass: profile

This issue was solved on Bugzilla Bug 100788

Threre is an issue on the GCC processor which crashes when it tries to process the#line directives during coverage compilation.

Solution: backport a patch from GCC 10 that fixes this issue

Oh, I see. The crash isn't really in the preprocessor itself, but the preprocessor is generating incorrect `#line` directives which cause the later profile pass to crash. So really two bugs, I guess. – Nate Eldredge Sep 30 '21 at 15:13
