You could try running mdrun through strace, if the latter is available on your 
system. (It should be present on most Linux systems.)

To do this, use "strace mdrun", which will print a list of the system calls 
mdrun uses up to the point of the segmentation fault. This might provide a 
clue as to what it is trying to do. Since it crashes pretty quickly, there 
shouldn't be too many calls to sort through.
