Hello There !
Do you use pfGeoSet::setBoundFlux ? If so, do you provide it with a valid
pfFlux ?
Your program crashes when it tries to evaluate the bounding box of a pfGeoSet.
Looks like your pfGeoSet has a fluxed bounding box, but the specified pfFlux
is corrupted (or not even a pfFlux).
If you have a small sample demonstrating the problem, please send it and I'll
try it here.
