Description
The following script segfaults in the `bytes(sig)` line
from PySide2.QtCore import QObject mo = QObject.staticMetaObject mm = mo.method(0) sig = mm.methodSignature() bytes(sig) # <- segfault here
Tested on macOS (10.14.6) and Linux (Mageia 7) with Python 3.7, PySide2 installed via pypi distributed wheels.
The backtrace from lldb is:
