[Python-bugs-list] [Bug #133096] Fatal python error in com_make_closure()

[noreply@sourceforge.net]

Bug #133096, was updated on 2001-Feb-19 09:03
Here is a current snapshot of the bug.

Project: Python
Category: Parser/Compiler
Status: Open
Resolution: None
Bug Group: None
Priority: 7

Summary: Fatal python error in com_make_closure()

Details: This construct causes python (2.1 alpha 2) to crash:

>>> def test(n):
...     return lambda fact: fact(fact, long(n))
...
lookup 'n' in test 1 -1
Fatal Python error: com_make_closure()

To try to help narrow it down, the following works with no problem:

>>> def test(n):
...     return lambda fact: fact(fact, n)

So it appears that adding the call to the long function is breaking
something.

This appears to work with the current CVS repository.  One of the
bug fixes this morning must have caught it.

OTOH, I've just rebuilt and it seems to have gone away.

A bug of this kind was fixed in revision 2.163 of compile.c (on
2001/02/12)- can you try after that?

Comment:
Nah, it crashes on linux too.

It doesn't crash if you change almost anything about the test-case, so it's
probably some bizarre kind of dictionary traversal bug again.

I probably should have added that I'm using the Win32 compiled version
downloaded from SourceForge (operating system is Windows 2000).
