At least one other user has identified this problem (running T31 or higher
resolution CCM3 under Solaris), and we have been able to reproduce it. The
user who first identified the problem said that the problem had to do with
an inadequate maximum stack size under Solaris. The proposed fix is
typing "unlimit stacksize" (under C-shell), or possibly "ulimit -s unlimited"
under other shells. We are in the process of verifying that this fix works,
but this should at least give an idea of where to start.
