Hi Haoyu,

Sorry for the incomplete report last night. It was very late here.

Below is a valgrind output. This is with Python 2.6.2 compiled from sources under Fedora 8 x86_64. I've also seen the error with Python 2.6.4, I'm pretty sure, but I'll double check. I'll also try compiling everything with debug symbols to get line numbers. I'll let you know what I find.

Ralf

P.S.: My file with the valgrind suppressions is here:
