[PD] Gem 0.91 CVS bug ?

[Jerome Tuncer]

Thanks for the quick answer Iohannes,

You guessed right: I do use N-Vidia's non free drivers (plain linux 
kernel nv drivers giving poor OpenGL results) and the latest c++ 
compiler from unstable.

Is there a workaroud?

You seem to infer so in the bug-report page but I don't quite get it...
Is it enough just to try and compile Gem with another (earlier version) 
of gcc/g++?

I'm not so confident about how to do it anyway but if it's a solution, I 
can try it (-:
