Because of Michael Hudson's request, I tried running Purify --with-pymalloc enabled. The results were a bit surprising: 13664 errors!

All the errors were in unicodeobject.c. There were 3 types of errors: Free Memory Reads, Array Bounds Reads, and Unitialized Memory Reads. The line #s were in strange places (e.g., in a function declaration and accessing self->length in an if clause, after it was accessed w/o error). The line #s are primarily: unicodeobject.c:2875, and unicodeobject.c:2214.

Might this have something to do with

bug [ #495401 ] Build troubles: --with-pymalloc

http://sourceforge.net/tracker/?func=detail&atid=105470&aid=495401&group_id=5470

?

Is there a reason one of the fixes for this problem hasn't been checked in yet?

Cheers, M.
