A similar problem was reported as bug #20
http://sourceforge.net/apps/mantisbt/ipe7/view.php?id=20
I have no idea what could cause this. Ipe does not actually call malloc
and free, but relies entirely on C++ constructors and destructors. I
suspect there is a problem with binary compatility of libraries.
It would be good if someone could figure out where in Ipe the crash happens.
