Hi,
I'm trying to use the ParaView (latest git version) python API from
within pure python and I'm running into an issue. The script I'm testing
runs the sphere animation example from the PV wiki, and while the
animation shows fine, the script crashes at completion on both Ubuntu
12.04 and OSX 10.8.4, with slightly different error reporting.
Everything works fine if I use pvpython (both with and without wrapper
script), but I don't see why pure python should be a problem. I've
attached the wrapper script I use to setup the environment (taken from
suggestions on PV wiki) and the script I'm testing. Below, I've shown
the errors seen. Has anyone seen this before? Is there some extra setup
bit that pvpython is doing that isn't being taken care of by the wrapper
script?
Thanks,
M

On Ubuntu, I usually see the following error:
*** glibc detected *** python: corrupted double-linked list:
0x0000000003064250 ***
Occasionally, I'll get:
*** glibc detected *** python: double free or corruption (!prev):
0x0000000003cd12a0 ***
and a long error report.
On OSX, I see:
