Description
Crash report
What happened?
This is the issue found while debugging #113566. I have not been able to extract a proper minimal viable reproduction code. It does seem to depend on whether some things are tied to asyncio.
This happens upon exit.
I will try to isolate a better case, but in the meantime, in case someone knows the ins and out of the expat mechanisms and has an idea about it, here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.
