Can you tell me what platform and architecture? Can you run it with gdb and get a stack trace?

Can you tell me what platform and architecture? Can you run it with gdb and get a stack trace?

This is on macOS 14.5 arm64.

I am not sure gdb is working on arm64 now, but I can do it on PowerPC.

I don't have the ability to debug on that platform, so any extra info you can give me will help. I can try address sanitizer and see if it comes up with anything.

Has it been confirmed to work on any non-x86 platform?

@jarro2783 Looks like the problem is specific to arm64 or Sonoma. At least on 10.6 powerpc everything works fine, both for 3.2.1 and 59656709c0c58fcd0ed18b38e02938dbe05284c5 (current master):

The UB sanitizer found an potential integer overflow. I don't know if arm aborts on that. If you can get a stack trace that would be great.
