Dear Maintainer,

Future versions of firefox-esr will contain code (related to security)
that currently fails to compile with GCC 12.2. The failure is a
regression from GCC 11, and was fixed in 12.3. Applying the patch[1] to
12.2 fixes the build issue. The corresponding upstream bug report is
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107461.  Interestingly,
there is another patch in the bug, but it's somehow not required.

Could you apply the patch to 12.2?
