[Bug 1979054] [NEW] gcc crashes on LP, needs updating

[stsp]

Public bug reported:

Currently the bad gcc release
appeared on LP for ubuntu-20.04
and 21.10 (22.xx are OK).
It simply crashes, you can see
the logs here:

I filled the upstream ticket:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105936
and as the result, they back-ported
the previously existing fix to gcc-10
branch:
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=f2851a7cff4d74edca26d39c7bfa1264355a22ed
They say that the gcc-9 branch is
EOL and won't be updated, so this
needs to be done by hands by ubuntu.
Fortunately the patch is very small
and can be trivially back-ported.
