I get this warning from my test suite when I introduced a segment of code:

python(18603,0xa000d000) malloc: *** Deallocation of a pointer not malloced: 0x310caa3; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug [snip] Sorry if this is all very vague, I'm just a bit stumped and wanted to see if anyone had some suggestions.

You may want the python-list mailing list or the equivalent comp.lang.python newsgroup, unless this is a bug with Python itself (you may try running Python 2.4.4, which is the next bugfix of the Python 2.4 series).

Regardless, you can help those who want to help you by providing the code that you have written that causes the error. A doubly nested try/except isn't all that exciting, so I would guess many would be surprised that you are getting double free errors.
