Group: V 2.32 release
Resolution: Fixed
Category: Python

%%%If you call Blender.Redraw from an autoregistered
script, Blender segfaults just after printing either
the message:
"Memoryblock free: pointer not in memlist" or
something about a double-free [seems to randomly select
one but "...not in memlist" is more common].

A test script:
- 8<-------------------

!BPY

"""
Name: 'Test'
Blender: 231
Group: 'Misc'
"""
import Blender
Blender.Redraw ()
- 8<-------------------

This happens in 2.32 and the latest CVS [March 15th
2004]. I'm running Linux i386, 2.6.3 kernel, 3D card is
an nVidia GeForce MX 440.
