"Segmentation fault" is a generic indication of something going 
catastrophically wrong. If grompp works on other library files (go and 
test it if necessary!) then you've probably mis-formatted ff_dum.itp and 
need to compare it with the correct ones and/or the information in 
chapter 5 of the manual.
