I believe this shouldn't be related to the project code, but to compiler options.

which options ?

[Xottab-DUTY]

I believe this shouldn't be related to the project code, but to compiler options.

which options ?

Those that enable enhanced instruction sets like AVX, AVX2, AVX512.
Maybe, the engine was compiled with some of these, but your CPU doesn't support it?

What combilator was used for the build? I've seen this behaviour in clang, try rebuilding gcc (or vice versa, what the hell)
Also try rebuilding with the -march=native flag, maybe it will eliminate generation of unsupported instructions.

I suspect that it's not the problem about extended instruction sets like AVX, etc.
It seems that probably xr_fixed_map got corrupted or corrupted item was added to it.
Clang-compiled binaries are known to be less stable than GCC-compiled ones, because this code base was written for MSVC and GCC has better compatibility with MSVC quirks it seems. On other hand, Clang is more strict and probably because of that the compiled code breaks sometimes.
I saw that there are flags in Clang that enable better compatibility with MSVC. Maybe they can help?
