[Python-Dev] assert failure on obmalloc

[Jeremy Hylton]

Failure running the test suite today with -u compiler enabled on Windows XP.

test_logging
Assertion failed: bp != NULL, file
\code\python\dist\src\Objects\obmalloc.c, line 604

The debugger says the error is here:
 	msvcr71d.dll!_assert(const char * expr=0x1e22bcc0, const char *

I've been seeing this sort of error on-and-off for at least a year
with my Python 2.3 install.  It's the usual reason my spambayes
popproxy dies.  I can't recell seeing it before on Windows or while
running the test suite.
