It seems something hapened to pgo-enabled gcc14 between pre20231022-r1 and pre20231029; since pre20231029 I've not been able to go to the next pre-release when having pgo enabled. Recompiling pre20231029 with USE="-pgo" it can compile the next pre-release just fine.

Created attachment 874892 [details] gcc14 build.log
sys-devel/gcc-14_pre20231015-r1 seems to have problems, too. Can build sys-devel/gcc-14_pre20231015 with/without pgo from my stable pgo-enabled gcc13. Cannot build sys-devel/gcc-14_pre20231015-r1 with/without pgo from my stable pgo-enabled gcc13. Can build sys-devel/gcc-14_pre20231022 with/without pgo from my stable pgo-enabled gcc13. Can build sys-devel/gcc-14_pre20231022-r1 with/without pgo from my stable pgo-enabled gcc13. Can build sys-devel/gcc-14_pre20231029 with/without pgo from my stable pgo-enabled gcc13. Can build sys-devel/gcc-14_pre20231105 with/without pgo from my stable pgo-enabled gcc13. Can build sys-devel/gcc-14_pre20231112 with/without pgo from my stable pgo-enabled gcc13.
Original report was on forums at https://forums.gentoo.org/viewtopic-t-1165840.html. I might need you to try bisect given I've no immediate guesses. Not looked into it yet, but I can't reproduce either.
Well - don't know if this should be marked invalid? I decided to rebuild libtool/glibc/binutils and a few other packages, went from gcc13 stable to gcc-14.0_pre20231112 pgo, and then to _pre20231119 and now to _pre20231126 without issues.
Weird. Given nobody else has reported it, let's call it WORKSFORME. Let us know if it returns.
Having hit this myself today, I now know it was caused by mold. The recent 2.4.0 release works though.
It is very likely the same as https://github.com/rui314/mold/issues/1151, which is fixed in mold 2.4.0, so please use mold 2.4.0. Sorry for the trouble.
