AMBER: DNA tutorial, in vacuo minimization

I am unable to run 'in vacuo' minimization for the DNA tutorial. When running
the minimization script from the webpage (below), I get a "Segmentation fault
(core dumped)" error. The output file I get is attached. I am running Amber 8
on SGI/Irix 6.5. I am told it was set up for MPI, but I am only attempting a
single processor run.

Interestingly, by changing only "igb=0" to "igb=1", the minimization does run
completely; but this is no longer vacuum. Please help me find a way to make
this work in vacuo.

Thank you,
Amanda
