Unfortunately I can't seem to get anything intelligible from lldb here (likely "skill issue"), and I can't reproduce it with the assets runfo provided. I get a clean run on alpine arm64.

The crash appears to be caused by access of uninitialized pointer:

Either from #113772 or #113711.

[jakobbotsch]

Most likely fixed by #113879. Let's keep an eye on the table.
