Hi all, I have an application which is getting a segmentation fault when releasing an autorelease pool, but weirdly, it seems to be happening only on earlier OS versions. I and another person have tested it on Monterey and it works, but a tester has High Sierra and it's crashing.
I have tested it on my system for zombies, with address sanitizer turned on, everything I can think of, and no issues.
This is part of the the stack trace:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x000070ff5dfdbec0
Exception Note: EXC_CORPSE_NOTIFY

I am at a bit of a loss as to how to debug this, since nothing is turning up on my system, and it seems to be occurring only on an older version of the OS where I can't debug it.
Any clues or ideas for how to track it down would be most welcome.
