Hello,
The following Python (2.7) application results in a SIGSEGV in the last
line.
Unfortunately, I don't understand why.
I guess that the Foo() object is deleted too early, although similar
constructs (in the OK section of the program) work just fine.
from PyQt4 import QtCore
import faulthandler
class Foo(QtCore.QObject):
sig_value_changed = QtCore.pyqtSignal(object)
a_list = []
def bar(self):
print("bar")
# OK
faulthandler.enable()
Foo().bar()
x = Foo()
x.sig_value_changed.connect(lambda: None)
Foo().a_list.append("x")
# SIGSEGV
Foo().sig_value_changed.connect(lambda: None)
Is this a bug? Or am I missing something?
Thanks in advance,
Marc
