Blender Segmentation fault When Using defocus node

When I try to use the Defocus node during postpro blender returns defocus: Processing Line 465 of 1080 … Segmentation fault.

Its always around line 465
My ram as far as I can tell is not faulty… though LMMS also segmentation faults within minuets on me

This has occurred in both 2.56 and 2.57:eek:

Any thought on how to fix this is appreciated

Turns out that it is just the blend file that does it and there is one camera in the file that does not do it. so If necessary I can just append everything to a new file

32 or 64 bit Blender?
You might simply run out of memory. Nodes and compositing eat away tons of memory.
And if the 32bit version has to allocate beyond, whatever a windows thread is allowed to allocate (it´s not 4GB), you get a segmentation fault.

Its 64 bit with 8 gigs of ram nowhere near maxed out when rendering

I´d file a bugreport then.
Sounds like a pointer missplacement or a wrong free or (re)(m)alloc.

If the crash is 100% reproduceable even better :slight_smile:

Ok thanks for the help. Will check bug tracker

The crash is about 85% reproduceable
