Crash report
What happened?
There is an assert in sysmodule.c that makes the interpreter abort when calling sys.audit with a non-string value in debug builds:
|
assert(PyUnicode_Check(args[0])); |
Python 3.14.0a1+ (heads/main:c5b99f5c2c, Oct 26 2024, 12:35:53) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.audit(9)
python: ./Python/sysmodule.c:522: sys_audit: Assertion `PyUnicode_Check(args[0])' failed.
Aborted (core dumped)
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.audit isn't a string:
