#302 filter_plymc.cpp causes assert

[Anonymous]

Meshlab trunk version: 5640

When running this filter on a mesh generated by a marching cubes algorithm, I get this assert:

meshlab: ../../../vcglib/vcg/simplex/face/pos.h:186: void vcg::face::Pos<facetype>::FlipF() [with FaceType = CFaceO]: Assertion `f->FFp(z)->FFp(f->FFi(z))==f' failed.</facetype>

Program received signal SIGABRT, Aborted.
