Thanks, this is actually helpful! At the risk of being flamed to death, I 
used Gemini to explain the cause of the crash. It suggests that this is a 
pointer underflow specifically on aarch64, because the calculation of the 
array size in that function is wrong. It suggests this patch:

  	do {
  		*z = y;

It also suggests that the code is lifted from musl libc :)

Can you try recompiling goffice0.10 with this change?

Thanks!
