I tried to compile the code using g++4.4.6 on aix 6.1. I dont have gdb installed.
After compilation, It is showing Segmentation Fault error:-

../test/Corner.h: In member function 'void VirtualFlow<T>::vector_flow(typename T::Data**, typename T::Data**) [with T = NProcess<or_func<NetAndVal<ZVal2>, with_derivatives>, ConvexNoOverlapSize<16, 16, Multiply<65536l, AllPass<CornerT<NetAndVal<ZVal2> >, NoFlow<CornerT<NetAndVal<ZVal2> > > > > > >]':
../test/Corner.h:369: internal compiler error: Segmentation fault

I tried to use -g option with to create .o file and looked for the problem. 

opt/freeware/bin/g++ -g ConnectFlow2.C -o ConnectFlow2.o

but I was not able to debug.

Please share good practices of how to debug the segmentation fault.

Thanks.

    I suggest upgrading your GCC compiler (since your old 4.4 compiler crashes). Try to get the GCC 4.6 source code then build it.

    Don’t forget to worry about dependencies, and to carefully read and follow the installation instructions (in particular, don’t build in the source directory!).

    If you really want to debug your compiler by yourself, rebuild it from source and recompile it with -g
