These stacks are really bad. I don't know if there's a known issue with stack walking. Maybe with better stacks this would turn into some existing shutdown hang.

I have looked into the generated symbol files and how the stack walker is handling them but there isn't anything that's standing out: the CFI directives appear to be complete and the stack walker isn't encountering anything odd until the frame in mozglue. A normal stack frame of a crash like that on macOS should look like this though:

This is x86-64 while the issue here only seems to apply to AArch64 so there might be either a bug in CFI generated for that platform, a bug in the stackwalker or a bug in the debuginfo. I'll open a separate bug to investigate.

For some reason, my problems only seemed to start with the update to 98.0
I have trouble loading the internet, then when I close firefox, it stalls & crashes :(
Here are my bug reports:

Closing because no crashes reported for 12 weeks.
