AMBER: xleap segmentation fault on SaveAmberParm

From: Brendan Duggan <bmduggan.musc.edu>

I tried to post this a few weeks ago but it seems it never made it to
the mailing list. My apologies if this is a repeat.

I've been trying to create a prmtop file for a sphingolipid, however
xleap (Amber9 and AmberTools versions) crashes and issues a
"Segmentation fault" when I issue the SaveAmberParm command. The
AmberTools version of xleap gives a bit more information on crashing.
Here's the output I get:

> /opt/amber10/bin/xleap -s -f glccer.leaprc
-I: Adding /opt/amber10/dat/leap/prep to search path.
-I: Adding /opt/amber10/dat/leap/lib to search path.
-I: Adding /opt/amber10/dat/leap/parm to search path.
-I: Adding /opt/amber10/dat/leap/cmd to search path.
-s: Ignoring startup file: leaprc
-f: Source glccer.leaprc.
/opt/amber10/bin/xleap: line 9: 13401 Segmentation

I/opt/amber10/dat/leap/lib -I/opt/amber10/dat/leap/parm -
I/opt/amber10/dat/leap/cmd $*

The number between "line 9" and "Segmentation fault" changes with each
crash. The file "glccer.leaprc" is as follows:

source leaprc.gaff

# load residues

LoadAmberPrep sphingosine.prepin
LoadAmberPrep glucose.prepin

# set connection atoms to link residues

set h1 element H
add GLCCER h1
bond GLCCER.STE.O2 h1

# save prmtop and inpcrd files
SaveAmberParm GLCCER glccer.prmtop glccer.inpcrd

The prep files stearate.prepin, sphingosine.prepin and glucose.prepin
were prepared using GAFF and are attached.

Can anyone tell me what I'm doing wrong?
