Uh oh!
There was an error while loading. Please reload this page.
syslog_get_argv() took sys.argv[0] with PyList_GetItem() and increfed it
only afterwards, so on the free-threaded build a concurrent replacement of
sys.argv[0] could free it in between. Use PyList_GetItemRef() instead.
(cherry picked from commit e5e0748)
