I posted an issue with the Nasa Overflow 1.8 code and have traced it further to a program failure in the malloc

areas of the code (data in these areas gets corrupted).  Overflow is mostly fortran, but since it is an old program,

it uses some c routines to do dynamic memory allocation.  Im still tracing down the problem, but could you enlighten me as to

how OPENMPI does the malloc_hooks and intercepts memory allocation calls to run on a linux myrinet cluster.

Is there any easy way to debug what is happening?? Im using brute force to track it down.
