[Wien] Segmentation faults (dstart/lapw2/maybe elsewhere)

[Laurence Marks]

I'm posting this for reference, mainly because we ran across it on my
older cluster with the more recent ifort and I think the solution was
lost form the Wien2k mailing list.

To avoid them, one needs to ensure that "limit stacksize unlimited" is
correctly set in all possible cases. Depending upon the OS it may be
enough to include this line in your $HOME/.cshrc, but you might have
to add it to $WIENROOT/parallel_options and/or /etc/csh.cshrc.

N.B., It's probably not "right" for siteconfig to do this, some
sysadmins might object, but it might be a useful idea to modify
siteconfig to test this and advise the user to set this up correctly.
