Hi Hannes,

I had a question about what we could do to detect this problem without 
address sanitizer, and ended up writing a patch ( 
https://sourceware.org/pipermail/gdb-patches/2024-October/212723.html ) 
which unfortunately I cannot test.

It would be great if you or anybody else with a windows setup could test 
that patch.

Thanks,
- Tom
