[Wien] A problem with icc and wien2k

Of course, the problem with lcore also disappear when you recompile with
"-O1".
At least now, TiC seems to get closer numbers obtained from previous wien2k
and ifort version compilers.
Someone should enter in the intel forums and try to get a solution from
intel, hopefully for the next ifort compiler versions.
Cheers
Cesar

Hi again,
It seems that lcore too in TiC example.
start (Wed Feb 23 16:11:44 GMT 2011) with lapw0 (40/99 to go)

Thank's for this info.
So it seems that beside lstart also lapw0 and txspec need to be recompiled
with -O1 !!!
------ ----- ------
I continued to trace the lstart problem. This compiler version is really
stupid:
in case.insld.f insert:
...
DO 119 I=1,NORB
NMAX(I)=NP
L=1
J=NQN(I)-NQL(I)
IF((J-2*(J/2)).EQ.0) L=-L
DQ1(I)=L*NK(I)/IABS(NK(I))
print*,'stupid print to fix ifort12 bug',i ! insert this line
IF (NUC) 111,119,111
111 IF (NK(I)) 112,119,119
112 DQ1(I)=DQ1(I)*(NK(I)-DFL(I))*DVC/Z
119 CONTINUE
....
This print statement inhibits the "overoptimization" due to the compiler and
one can
compile with -O2. (during execution you will get several reminders about the
stupidity of the compiler)
PS: It does not help to set nk=999 at the beginning of insld.f
