[Wien] New findings on the lapw0 seg fault core dump error

[Michael Fechtelkord]

I debugged the core-dump file with gdb and using debugging symbols in 
compilation of lapw0.

The debugger gave me the line which causes the coredump

_----------------------------------------

Debuginfod has been enabled.
To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `/usr/local/WIEN2k/lapw0 lapw0.def'.
Program terminated with signal SIGSEGV, Segmentation fault.

*1649    !$omp parallel do reduction(+:rhopw00,cwk,cvout) &*


[Current thread is 1 (Thread 0x14823edbe740 (LWP 339344))]

------------------------------------

Maybe somebody has an idea how to fix it..


Best regards
