Hi, I agree that it sounds like some sort of gcc bug, or maybe a bug in circulators implementation. Two versions of a code doing obviously the same thing but one of them crash, I've seen that before. If I have a chance I'll send you a short "hello world" program with c++/cgal to see if you can reproduce the bug with your system. If so we can report it.
If the above "verbose" code fix the problem that is great, I'll push it to trunk.

The segmentation fault also occurs for a debug compiled version and yields the attached core dump. Interestingly, the DFNFlowEngine does not crash for a non-optimized debug compilation of the same sources. Description of failure: According to the core dump, the failure can be traced back to DFNFlow.cpp:176, where it is checking if the cell is inifinite (although I have also had it fail at the permeability assignment directly below line 176 for a modified version of DFNflow.cpp). DFNFlow.cpp: 176: if ( Tri.is_infinite(cell1) || Tri.is_infinite(cell2)) cerr<<"Infinite cell found in trickPermeability, should be handled somehow, maybe"<<endl; 177: cell1->info().kNorm()[facet->second]=cell2->info().kNorm()[Tri.mirror_index(cell1, facet- >second)] = pow((aperture+residualAperture),3)/(12*viscosity); I am unsure why this line is causing a crash in the optimized-debug compiled code, but not the non-optimized-debug compiled code. My optimized-debug compiled executable is simply built with the flag -DDEBUG=ON. My non-optimized debug compiled code uses an edited CMakeLists.txt to avoid optimization: IF(CMAKE_COMPILER_IS_GNUCC) SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -O0") SET(CMAKE_C_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -O0") ENDIF(CMAKE_COMPILER_IS_GNUCC) The attached zip contains: mwe.py // input script liteSpecimen2mm.spheres // packing file jointSurf.stl // stl for smooth joint coreDump2.txt // core dump after executing mwe.py with optimized debug compiled yade Any assistance with this bug is greatly appreciated.
