[Message part 1 (text/plain, inline)]

Resending my e-mail for Debbugs tracker, again.

Hi, I've tried looking at one of the failing packages - motif. It seems
to me it is probably failing because of gcc-14, so I wanted to try with
gcc-11 to verify that.

(The error it fails with is implicit declaration of strncmp in seemingly
generated file. I think some kind of generation/copy of C code is failing in
the package with gcc-14 source, but I haven't really checked further and
didn't want to spend too much time on it)

That leads to a build of libstdc++-11.5.0 as libstdc++ is built for the
gcc version used in updates to core-packages-team. (since 323483163e1453498f25caf254851a1f6fb817c7)
But this is failing for me locally. Specifically with
internal compiler error! :(

Any ideas? I am completely lost. Attaching the log.
