The following attatchment from the cpu20006 benchmark leslie3d ICEs in the
following manner. The problem appears to be a latent bug that has come and gone
a couple times (I saw it earlier on the gamess benchmark too). Recent
mainlines compile it fine, but revision 128829 exhibits the problem. Opening a
bugzilla since I haven't been able to spend as much time digging into it as I'd
thought/hoped, and don't want to lose track of it.
