Valgrind + Python: __strcpy_chk warning in PyImport_ImportModuleEx

[Ivan Gyurdiev]

Can someone suggest the cause of this warning?
Should I file a bug? Against python or glibc?

This is python code being valgrind-ed on x86_64.
The suppressions file here: 
http://svn.python.org/projects/python/trunk/Misc/
is installed, and additional suppressions for Memcheck:Value8 and 
Memcheck:Addr8
have been added in PyObject_Free and PyObject_Realloc.

As a side node, why is this suppressions file not installed by default?
