[Wien] Segmentation Fault in lapw0

[Torsten Andersen]

Dear Sam,

the problem is probably with your shell settings.

in bash, you need to put (in the file where you defined WIENROOT - 
.profile or .bash_profile, probably): ulimit -s unlimited

in tcsh, you need to put (in .cshrc or .tcshrc - wherever WIENROOT is 
set): limit stacksize unlimited

If this doesn't help (log out and log in again for the settings to take 
proper effect), you can try to recompile with "-O0" 
(minus-the.letter.O-zero).

Best regards,
Torsten Andersen.
