Crash report
What happened?
Hello,
In the CI of cloudpickle, we encountered a crash of the python interpreter due to a stack overflow with python3.14.0a6.
Reverting to python3.14.0a5 fixes the error.
This might be related to GH-130398, with a bad detection of the limit of the stack?
I could not test it locally as I don't own a mac.
class A:
def __getattribute__(self, name):
return getattr(self, name)
a = A()
print("Testing Recursion Limit")
try:
a.test
except RecursionError:
print("Recursion Limit ok")Output with python3.14.0a5:
Testing Recursion Limit
Recursion Limit ok
Output with python3.14.0a6:
Fatal Python error: _Py_CheckRecursiveCall: Unrecoverable stack overflow (used 3923 kB)
