Hi, I updated to the latest CVS, no change. However, I started digging around some more myself, I believe the problem is that pthread_create() doesn't like running an embedded function. When I get rid of the embedding it seems to work again. Anyone else has some experience/comments on this, or should I just clean this up into a patch you can apply?
