[New-bugs-announce] [issue35484] Segmentation fault due to faulthandler on Solaris

New submission from Jakub Kulik <kulikjak at gmail.com>:
When running tests on Solaris (amd64) I noticed that one test in test_faulthandler.py fails with the segmentation fault.
I have attached program reproducing this issue and its core stack trace. Program runs entirely with *Ending* printed as well and segfaults somewhere in the sys.exit() during deallocation.
Problem doesn't appear when chain variable is set to False or if faulthandler is unregistered. Also, this bug appears only with --enable-optimizations on, but probably it just doesn't manifest itself in non optimized build (or on sparc).
I am not sure how to diagnose it more so I am at least reporting this issue.
