I tried without supernovae and my code behave differently, but it still doesn't work. All I get is either a bus error or a seg fault, depending on using '--cfg=contexts/factory:thread' or not.

Yes that's right. I found files named ucontext.h in two places: /usr/include and /usr/include/sys/
but though they have the same name, they're quite different. Do you want me to join them to a mail ?

As I said, it doesn't work. But I noticed two other weird (for me, at least ! ;-) ) things:
When I launch cmake, I can see this message: 'System processor: amd64' whereas my processor is an Intel Core I3.
And 'Ucontext can't be used with this version of gcc (must be greater than 4.5)'. As far as I remember, my gcc has the same version as Snow Leopard one.
Have you got some more ideas ?
Thanks for your help !
