Tad too slow ;)
(In reply to immolo from comment #3) > Tad too slow ;) The other bug is an ICE, even though it's still protobuf, it's not related to this one. Also, someone should change the title, so dev-python/ isn't omitted.
Looks like I've been staring at bugs too long, thanks! I'll fix as you suggest now.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d2facc542948cfb79193220e7beb9d1c9837df8a commit d2facc542948cfb79193220e7beb9d1c9837df8a Author: Sam James <sam@gentoo.org> AuthorDate: 2024-11-19 03:48:42 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2024-11-19 03:52:22 +0000 sys-devel/gcc: backport C23 fix to 15.0.0_pre20241117 Backport a -std=gnu23/-std=c23 fix to 15.0.0_pre20241117 which prevented coersion from _Bool to NULL. Note that this is still dodgy code and some are proposing this be banned in a future C version (maybe even C2y), but it shouldn't be rejected in this version at least. I've added Closes tags for all bugs which, at a glance, look related, but I haven't re-tested them all and one or two might need reopening.
