Re: Compute the intersection of two fans

Hey juergens, unfortunately (well... maybe fortunately *g*) I could not reproduce this segmentation fault. With a fresh 2.13-1 it works fine here. But this can have several reasons.

Re: Compute the intersection of two fans

This issue will be fixed in the next perpetual beta version. In the meanwhile here is a patch for it. Just apply it like in the previous post. Please report back if it works. I did not try your example, since I do not have atint installed at the moment.
