Quite likely a 32-bit specific problem.

Could anyone install dmalloc and configure gromacs to build with dmalloc 
and run the test with the new mdrun?

I did mine and found that it was due to one line in mshift.c 
"srenew(g->edge[0],n); "

mdrun output:
realloc for g->edge[0] (24 bytes, file mshift.c, line 251, 
g->edge[0]=0x0x       1)
