[glob2-devel] crash

[Stéphane Magnenat]

Hi,

I've got a crash using OpenGL with latest hg master. I allow myself to post 
this bug here as an answer to the lates mail that stated that this bug 
disappeared.

I think there is still a memory trash. We should run it inside valgrind. 
OpenGL was on, so perhaps the bug is in the GL code.

Have a nice day,

Steph
