--- Comment #254 from Larkin Nickle <me at larbob dot org> ---
I've now tried 11.1.0 almost exactly as The Written Word builds it, and still
get:
during GIMPLE pass: dce
../../libiberty/mkstemps.c: In function 'mkstemps':
../../libiberty/mkstemps.c:80:1: internal compiler error: Illegal instruction
80 | mkstemps (char *pattern, int suffix_len)
| ^~~~~~~~
libbacktrace could not find executable to open
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
This happens against binutils 2.30 as TWW builds it, and against 2.36 or 2.37.
I also have to enable a version of gcc-11.1.0-PR64919.patch with #undef
MAKE_DECL_ONE_ONLY removed in order to build libgcov at a lower optimization
level to even get to this point. TWW gets this issue with 10.3, but not 11.1
for some reason.
