[Wien] Segmentation fault in lapw2 using IFORT 10.1.x

[Florent Boucher]

Dear Gerhard,
I just want to come back to your previous message concerning IFORT 10.1.x
I was able to reproduce exactly the same behavior (10.1.11). Do you have 
found something more on l2main to explain the problem or may be someone 
else ?
Also, I am not so use to modify the makefile so if you did a specific 
modification for l2main in your make file, I will appreciate to have it.
Regards
Florent
