wmayer 2012-11-27 19:35 administrator ~0002588 Last edited: 2012-11-28 08:34	Using OSD::SetSignal() works very well and catches all segmentation faults and converts it into a Standard_Failure exception. According to the examples above the function OSD::SetSignal() needs to be set only once. I first tried it inside initPart() but this leads to a crash of the application under Windows -- seems some conflicts with python. On Ubuntu 10.04 everything works fine. Moving it into Part::Feature::recompute() as static bool first = true; if (first) { first = false; OSD::SetSignal(); } works on both systems. EDIT: On Windows the OSD stuff seems to work only with VC++ compiler but not MinGW. With the latter we still have crashes. Note: When applying the refinement algorithm on the pad then the filleting works with all radii.

wmayer 2012-11-28 09:05 administrator ~0002589	This bug should be fixed in 0.14 as at the moment it's not clear if it causes some regression to the imminent 0.13.
