Summary: profiler: Bad return and Bad call errors with exceptions
Initial Comment:
I ran into a weird error when trying to profile a test
script of mine:
AssertionError: ('Bad call', ('', 0, 'encode'))
I managed to whittle it down to some minimal test
cases, which are attached (although the errors they
generate are slightly different.)
$ python-cvs -m profile profile_badcall.py

The errors occur in python CVS as of 20050206 and
python 2.4, but not in python 2.3.4.

I still see this in current python 2.4, but not in current
python CVS.
Also, hotshot seems to work ok in 2.4 and CVS.

Is there any news on this bug? It is possibly preventing
scons (http://scons.org) from being profiled on python 2.4
-- we get the same errors as above. Test case is too large
to include here, but please email me with any news if
possible! Would be glad to test a fix.
