RE: Crash in python bindings on windows (in apache)

No, removing the atexit does not solve the problem. It still keeps
crashing, although in a different place (PyErr_Restore).

Marc, does removing the "atexit(apr_terminate)" function call solve
the problem? In Subversion 1.2, we did not automatically terminate
APR. Maybe we can find a different way to solve this problem, such as
by using the Python atexit module to call our apr_terminate function
while the Python interpreter is still valid?

Cheers,

David
