Summary: Multiple problems with GC in 2.3.3

Initial Comment:
Hi. We're running a multithreaded application that
spiders some web pages, and parses them. We've had 2
types of problems: one where we have the python process
segfault. Another where python spins in an infinite
loop. We are running on FreeBSD 4.8-RELEASE. We have
not had this problem with 2.2. We have this problem
with both 2.3.2 and 2.3.3. This is repeatable, and
we're willing to help in every way to fix this. I've
attached the gdb stack trace for the process that
segfaulted, and the process that spins in an infinte
loop. We attached to it in gdb and ctrl-c'ed to check
the status. There are 2 separate gdb traces in the
attached file.

Thanks

We are using pycurl. And we have reported it, in case. The
reason I'm reporting it here is that the stack trace does
not involve pycurl in any way. it seems to be python all the
way. I will build with pydebug and report back.

The only test case I have is the program we're running now.
We haven't yet managed to reduce it to a simple test case.
We're working on it. We would be open to figuring out a way
to give you access to the code itself...

Are you using the pycurl extension module?  If so, you should 
report your problems to the pycurl project too.  I don't know 
whether the problem *is* in pycurl, but the only reports of 
this type ever seen before have come from people using 
pycurl.  If you're not using pycurl, it would be good to know 
that too.

Have you tried building python --with-pydebug?  That may
lead to an assert or some other indication of the problem. 
Do you have a test case to reproduce this problem?
