I'm sorry that no action was taken on this bug report sooner.  There was no 
input file attached to the report, so I am unable to test.  However, given that 
over 8 years have passed, I'm closing this bug.  If you still encounter a 
segfault please open a bug with an example input file to reproduce the issue.
