In WIEN2k 17.1, is tol=1.e-3 in SRC_symmetso/symmetso.f on line 110 okay
or does the same change need to be made too? Thanks in advance.

Of course the error occurs always, also when running x symmetry.
In init_lapw in batch mode, the error is catched automatically and
init stops, while in the step-by-step initialization you are supposed
to examine case.outputs by yourself and find the problem on your own.
Just check the case.outputs file.
The problem is that this site has "almost" C3v symmetry and not only
C3i. The mirror planes and C2 operations are only slightly invalid and
the test in symmetry was not accurate enough.
Edit symmetry.f in SRC_symmetry and search for "tol".
Change the value of tol from 1.d-3 to 1.d-4:
tol=1.e-3 --> tol=1.e-4
Thanks for reporting the problem.
