Installs a fancy termination handler which prints a backtrace before aborting 00042 /*! This function needs to be called just once per program run, to 00043 install our termination handler; thereafter, if std::terminate() 00044 is called (e.g. due to an uncaught exception) it will call our 00045 fancy termination handler. 00046 00047 The backtrace (from /usr/include/execinfo.h) will be in a fairly 00048 raw format, e.g. with lines like the following: 00049 00050 /path/to/saliency/build/obj/nub/refdetail.so(_ZN3nub6detail22throw_soft_ref_invalidERKSt9type_infoRKN4rutz8file_posE+0xc3)[0xb79301f3] 00051 /path/to/saliency/build/obj/Neuro/ShapeEstimator.so(_ZN14ShapeEstimator7computeERK7Point2D+0x60b)[0xb7a556bb] 00052 /path/to/saliency/build/obj/Neuro/Brain.so(_ZN5Brain6evolveER7SimTimeR7Point2DRiRf+0x9ed)[0xb7afb0ad] 00053 /path/to/saliency/build/obj/Neuro/getSaliency.so(_ZN11GetSaliency7computeERK5ImageI6PixRGBIhEERK7SimTime+0x1ef)[0xb79e8cef] 00054 00055 That is, each line gives the name of the object file, followed by 00056 the symbol name of the function that was executing in that file, 00057 plus a code offset relative to the start of the function, plus a 00058 global address: 00059 00060 file.so(symbolname+offset)[address] 00061 00062 You can get somewhat prettier looking output if you pipe the 00063 backtrace through the c++filt program, which will demangle the 00064 function names and give you something like this: 00065 00066 /path/to/saliency/build/obj/nub/refdetail.so(nub::detail::throw_soft_ref_invalid(std::type_info const&, rutz::file_pos const&)+0xc3)[0xb79301f3] 00067 /path/to/saliency/build/obj/Neuro/ShapeEstimator.so(ShapeEstimator::compute(Point2D<int> const&)+0x60b)[0xb7a556bb] 00068 /path/to/saliency/build/obj/Neuro/Brain.so(Brain::evolve(SimTime&, Point2D<int>&, int&, float&)+0x9ed)[0xb7afb0ad] 00069 /path/to/saliency/build/obj/Neuro/getSaliency.so(GetSaliency::compute(Image<PixRGB<unsigned char> > const&, SimTime const&)+0x1ef)[0xb79e8cef] 00070 */ 00071 void invt_install_fancy_terminate(); 00072 00073 // ###################################################################### 00074 /* So things look consistent in everyone's emacs... */ 00075 /* Local Variables: */ 00076 /* indent-tabs-mode: nil */ 00077 /* End: */ 00078 00079 #endif // UTIL_TERMINATE_H_DEFINED
