Segfault opening cow.obj on Linux #25

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi all!

I have a segfault opening the cow.obj with the OBJImporter... :(

If I open the example and change cow.obj by the zombie obj it work.

This problem doesn't seem to be related to OBJImporter directly but 
cacheAlignmentData()

I suppose this problem is Linux specific. Can someone confirm this?

There was another user having issues on linux with some other obj, but on my 
mac it was fine.

I'd suggest investigating in the objLoader code, that should be the only place 
where we can have Os differences...
