New submission from Xinmeng Xia <[email protected]>:
The following program 1 can crash in Python 3. We have reproduce it in the
Python version 3.5, 3.6, 3.7, 3.8, 3.9, 3.10. This bug seems to be similar to
issue 36272, however, the tracking system shows issue 36272 has been fixed and
the program 2, which triggers issue 36272, will not cause crash (“core dump”)
in Python 3.8, 3.9, 3.10.
We have attached the stack trace in the end of this report.
Program 1:
========================
import logging
def rec():
try:
logging.error("foo")
except:
pass
rec()
rec()
========================
Program 2:
========================
import logging
def rec():
logging.error("foo")
rec()
rec()
======================
The error message is like following:
“
ERROR:root:foo
ERROR:root:foo
ERROR:root:foo
ERROR:root:foo
…
ERROR:root:foo
ERROR:root:foo
ERROR:root:foo
Fatal Python error: _Py_CheckRecursiveCall: Cannot recover from stack overflow.
