I added it to bugzilla here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111396
Since this only reproduces part of the issue, please let me test again with rustc_codegen_gcc after adding the missing fix. I confirmed that the fix is in https://github.com/antoyo/gcc/commit/9d5b6b20efa20825926196759d50706a604c64a8 so you might as well include all of this (except the linetable condition in toplev.cc).
