Bug#1121183: /usr/bin/x86_64-linux-gnu-g++-15: src/gallium/drivers/zink/zink_draw.cpp:671:49: internal compiler error: Segmentation fault
Package: g++-15-x86-64-linux-gnu

Dear Maintainer,
this is regression. gcc from Debian testing just few weeks ago was
working fine when compiling mesa from git.
But today I upgraded packages, and when building mesa I got things like
this:
```

The build process (as well as installing some dependencies using sudo),
can be replicated using this script at
https://gist.github.com/baryluk/1041204eff4cc4fad6f1508afe67b562
Then running it with `./mesa-build.py --build32=0 --debug=1` as a normal
user (it will create two directories `~/libdrm-git` and `~/mesa-git`,
and if build is successfull also `~/mesa-opt` and `~/zink-opt` script).
It will not modify or create any other files on system or user.
Few other files do also take forever to compile. Like 10 minutes, where
before it was few seconds. I never managed to wait long enough for it to
finish. Examples are `../../../src/mesa/vbo/vbo_save_api.c`
`../../../src/mesa/main/format_utils.c` but there are few more.
It is regression, as it was building all fine just few hours ago, before
I did system upgrade.
Here is a dump of the build script, showing some dependencies versions
