Subject: AMBER: AmberTools1.1 (and 1.0) antechamber endless loop

I am getting an endless loop with AmberTools1.1 and 1.0 installations on
different machines. I have tested this out to 1 hour elapsed time.
However, with AnteChamber-1.27, the command completes and does so in 8

The command is:

antechamber -fi mol2 -fo prepi -i chp3.mol2 -o chp3.prepin -j 5 -c bcc -s 2

The chp3.mol2 is attached.

Perhaps one of the developers could execute this in their AmberTools
environment to see what result they get there.

I have a tgz of the directory used for the run, and will send if anyone
wants to see that.

Is a different means of reporting a possible bug recommended?
