Hi pravav,

Without more code, it is impossible for me to suggest anything...

The problem comes indeed from fHandle, thus I need to know how this 
handle is initialized and which operations are made on the LCC after the 
initialization.


A last remark: if you are in 3D and if you want to have one dart per 
each vertex of a given face, a better possibility is to use:


for (LCC::Dart_of_orbit_range<1>::iterator pHandleBegin =
lcc.darts_of_orbit<1>(fHandle).begin(), pHandleEnd =
lcc.darts_of_orbit<1>(fHandle).end(); pHandleBegin !=
pHandleEnd; pHandleBegin++)
