[gecode-users] Heap memory exhausted when copying a model

[kTorpi]

Thank you very much.
Now when I use the clone function I get another exception: "Space::clone:
Attempt to invoke operation on not stable space" I've read in MPG that this
is because the space is failed or not stable, but I don't know what this
realy means. Why can my space be unstable? I can post constraints and I can
get the solutions, so everything seems to be fine.

Thanks in advance,
Steve
