[Wien] lapwso error

[魏诗如]

Dear Wien2k users/team:
I am running wien2k_21.1 on my linux system(CentOS 7.5.1804), compiling wien2k with these setting:
fortran:ifort
c:icc
parallel:mpiifort
fftw-3.3.10
elpa_2021.11.001

I have some question about SO calculation(run_lapw -so)

First, I perfromed a SR calculation and everything seemed correct. Then running init_so_lapw as default: SO for all elements, EMAX: 5.0Ryd, RLO: NONE, and non-spinpolarized.
When run_lapw -so,a error occurred in lapwso:

 LAPW0 END
 LAPW1 END
forrtl: severe (174): SIGSEGV, segmentation fault occurred

I searched the wien2k-mailinglist but it did not solve this problem. 
However, I found a bigger EMAX in case.in1 can help solve this problem well, and "RLO:ALL" sometime worked, too.

I wonder whether small EMAX will cause this error if compiling correctly, and what is the difference between EMAX in case.in1 and EMAX in case.inso.

Thank you very much.
