It's a big C program and you have to debug it as one.  Well, first of
all try upgrading to the newest versions and see if there is already a
fix.  Be especially suspicious of any C extension modules you're using.
There are also some compile time options that let you rebuild Python
with extra consistency checks for reference counts.  Turn those on and
see what happens.
