Hi everyone, today as usual I update the Live Ebuils with smart-live-rebuild, but gcc 15 fails because the patch 71_all_PR116878-libcall.patch fails to apply and I come to report this.
Yesterday there were no problems updating gcc, but today it seems that due to the commit fe9e53421889ec5d5c360107a8b9c80b95cbebcf (according to smart-live-rebuild, I tried to look for the commit but it didn't appear), the changes cause problems with the patch.
Here is the output of everything that went wrong:

Still, where can I report bugs like this in case I run into "failed patch" issues?
NOTE: I'm running the gentoo-source kernel which I didn't finish configuring, but that's not the cause of this.
NOTE2: I also have a live ebuild of gcc 14 installed, but I didn't test if I can upgrade.
I hope someone has a suggestion on how to fix this.

I tried updating GCC-14 and it had no problems compiling.

Live ebuilds track upstream as changes happen. This makes live ebuilds susceptible to patches spontaneously rotting when upstream modifies that same area. The patch will need to be updated or removed, depending on what upstream changed.

Fixed: Updated the repository and GGC 15 is now building.

And how do you report these bugs with the patches so that the Live Ebuild maintainer is aware of this? Also, the GCC 15 live ebuild is from the Gentoo repository.

For GCC in particular, a ping on IRC in #gentoo-toolchain usually works best, although I'm always watching the bugs for patches where we've added something (so it's usually a case of me being asleep when it got committed). Otherwise a bug on bugs.gentoo.org.
