Bug report

GH-94474 caused several buildbots with GCC to fail to compile_decimal module with--with-pydebug --with-lto option. The problem did not show up when I was testing my PR on the build bot farm. I can reproduce the issue locally with GCC 12.1.1. Build does not fail with non-debug builds. Only the combination of LTO and debug fails for me
