Crash report
What happened?
There is an assert in
sysmodule.cthat makes the interpreter abort when callingsys.auditwith a non-string value in debug builds:cpython/Python/sysmodule.c
Line 522 in f6cc7c8
This assert seems completely unnecessary, as the code that runs the hooks (which only triggers if there is some hook registered) will raise an exception if the first argument to
sys.auditisn't a string:I'll submit a trivial PR removing this assert.
