[MMTK] How to debug C code of MMTK?

[Andrei A. Korostelev]

Hi Konrad,
   Here is my story:
I modified one of the C coded routines in MMTK (for example, 
nonbonded.c) and compiled it. After this I have new MMTK_forcefield.so 
(this is the only object file that is different from distributed ones). 
When I try using minimization I get "segmentation fault".
   Here is my question:
How can I debug MMTK's C coded part? I have difficulty with debugging 
because all the commands are invoked using Python and there are no 
executables derived from C code.

Thank you.
Andrei.
