Those are the changes with the current behavior from the behavior in 3.5
observed at the time of the initial bug report:
python 3.7:
return.py Unchanged.
exception.py After a jump from the 'exception' event into the previous
statement, the ensuing 'step' command triggers a trace 'return' event.
jump.py The sequence of trace events is unchanged and Python aborts
now at the last 'step' command with:
python: Python/ceval.c:1083: _PyEval_EvalFrameDefault:
Assertion `STACK_LEVEL() <= co->co_stacksize' failed.
python 3.8:
return.py Unchanged.
exception.py Unchanged from 3.7.
jump.py The sequence of trace events is unchanged and the last 'step'
command prints now the cryptic error msg:
TypeError: 'NoneType' object is not callable
> /path/to/jump.py(2)gen()->0
-> for i in range(1):
Applying the last patch fixes both 3.7 and 3.8. I can build a PR from this
patch. An explanation should be given for the behavior of 3.7 and 3.8 in the
jump.py case.
