[GNUnet-developers] GNUnet crashing on BSD/solaris

Hi!

I've just identified the reason why GNUnet was working so badly under BSD (and 
probably solaris). The reason is, that GNUnet uses large (64k) amounts of 
stack allocated data (more efficient, no malloc/free). BSD has a default 
stack size of 1k and seems to be very intolerant (segfault with corrupted 
stack) when this limit is not obeyed. Yes, it is possible to set a higher 
limit, but GNUnet did not do that. 

Linux has a minimum stack size of 16k, but either it grows automagically if 
more is needed or overwrites other memory without segfaulting. Since the 64k 
were in practice not used by the current code, this is hard to say. Anyway, 
the code is being changed to create threads with sufficiently large stacks.
