Crash in the projection

[Cyrille Berger]

Hi,

I suspect it only happens on multicore system, and it's not easy to reproduce 
(especially when you are unlucky it happens when you don't want, and doesn't 
happen when you want :/ ). But I don't know enought of the multithreated 
projection system, I hope someone who knows can do something with the 
valgrind output in attachement. I am of course ready to help debugging if 
needed.
