bug#65640: 30.0.50; segfault when building emacs with native-comp

[LemonBreezes]

Hi. I updated from the unstable GCC 13.2.1_p20230826 Gentoo package to the live 14.0.0.9999 version of GCC and the issue disappeared. Thank you. :))

Looks like Andrea was right: libgccjit is segfaulting on your system,

for some reason.  If some other version of libgccjit is known to work

well on that platform, perhaps install that other version instead of

what you have now.
