--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> ---
Thanks. I was able to reproduce that. It's related to the usage of '#line XYZ'
directives which generate a situation where the function ends before it begins.
I was able to reduce that to something like:
$ cat x.c
void
foo()
{
#line 1
}
$ gcc --coverage x.c
during IPA pass: profile
x.c: In function ‘foo’:
x.c:1:1: internal compiler error: in coverage_begin_function, at coverage.c:662
1 | void
| ^
