I have used valgrind on python, but mostly the latest CVS version,
not 2.2.1. valgrind and python were built with gcc 2.96 (redhat 7.2).
I also use purify from time to time when it works (pretty rare).

Unlikely a python problem. I just tried valgrind with the current
CVS version of 2.2.1+ (what will eventually become 2.2.2).
There were no problems reported doing import math.
You can try several things to fix the warning:
* run without your module
* use a different compiler (version)
* run the CVS version: cvs upd -r release22-maint
* pass --workaround-gcc296-bugs=yes option to valgrind
