[Pyrex] pyrex 0.9.4.1 bugs?

[Chris Bainbridge]

I have a pyode (which uses pyrex to wrap ODE) application which is
generating odd failures, usually something like:

*** glibc detected *** double free or corruption (!prev): 0x0823d130 ***

Everything works fine with 0.9.3.1. I've looked over the archives at
noticed that a segfault generating bug was reported in May (thread
"Bug report on return inside a loop"). Did this ever get fixed? Also,
has anyone ported the pyrex testsuite to Linux?

Running valgrind over my application clearly shows some memory
problem. Log attached below.
