@marcan @falktx can you binary search the compilation, half -g, half -O, to find the offending function? Does the problem persist with inclining disabled?

@marcan @falktx by the way, is this Carla the sound software or Carla the autonomous car simulation system (my Google-fu finds two software by that name)

@mirabilos @marcan @falktx You don't even need LTO. Just use someting that is !Linux on AMD64 and you already get miscompiled. Latest example I encountered is Clang 15 on OpenIndiana. Seems to emit broken DWARF tables and then the unwinder cannot properly unwind.

@mirabilos @marcan @falktx If I would get a dollar every time I find a compiler bug because my test suite fails… I’d have gotten quite a few dollars. As soon as you leave Linux/amd64, things are incredibly broken. Both GCC and Clang.
