Yes, I can confirm this fix.
(I could not reproduce the problem, because I already had applied this
fix in my sources. This was done during the busy workshop,and I forgot
to document it).
Thanks for the solution.

I think I found the cause of the runtime gfortran compiled lapw0 error
given in the previous post below.
In SRC_lapw0/lapw0.F of WIEN2k 23.2 on line 2645, there is:
IF(GGA_SWITCH .eqv. .TRUE.) allocate( CFFT_STR_GGA(iff1,iff2,iff3,1:9) )
Also, on line 2651, there is:
IF(GGA_SWITCH .eqv. .TRUE.) allocate( CFFT_STR_GGA(1,1,1,1:9) )
One of the above two allocates CFFT_STR_GGA which should explain why
there is no issue when its a GGA calculation.
However, where the error seems to be happening with LDA is on line
2655 having:
CFFT_STR_GGA = ZEROC
The cause seems to be CFFT_STR_GGA being used without being allocated
in the LDA case (or more broadly when its not a GGA case). The error
goes away if the line 2655 is changed to:
IF(GGA_SWITCH .eqv. .TRUE.) CFFT_STR_GGA = ZEROC
Could another person confirm that as a solution or see a better fix
for it?
Thanks,
Gavin

Dear all,
I cannot use the Vxc option LDA to calculate any struct(i have tried different
materials). Everything is fine when doing init, but there is an error in scf.

My system is Ubuntu 22.04. And the complier is gfortran. i followed the step on
the pdf files provided by Gavin Abo to install wien2k.
And Other options have no problem.
Is there anyone have the same problem? How can i solve it?
Looking forward to your reply.
Best wishes!
Yuyang.
