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:
--- go-dtoa.c
+++ go-dtoa.c

It also suggests that the code is lifted from musl libc :)
Can you try recompiling goffice0.10 with this change?
Thanks!
