P4: Low Description
The following snippet segfaults while executing the last line:
from PySide6.QtCore import QObject, Signal, Slot class Foo(QObject): s = Signal(int) def __init__(self): QObject.__init__(self) def send(self, i): self.s.emit(i) f = Foo() f.s.emit(42) # ok Foo().send(42) # ok Foo().s.emit(42) # segfault
Regardless of whether calling the signal of a temporary directly is "allowed" as part of the API, it shouldn't segfault.
