[Wien] Segfault in runsp -so (lapw1), gfortran 6.4 on mac os sierra

[Gavin Abo]

In your traceback, there is:

#1 0x1090555ec in zlatd4_ 
/Users/hugstr/src/WIEN2k_17alpha_20170920_1100/SRC_lapwso/lap_bp.f:4427

On line 4427 of SRC_lapwso/lap_bp.f in WIEN2k 17.1, there is:

ABP(I1I)

In the same file,

Line 4212 has:

COMPLEX*16   ABP( * )

Line 4242-4243 has:

!  ABP     (input/output) COMPLEX*16 array,
!          dimension (1:n*(n+1)/2+(n/hb+1)*hb*(hb-1)/2)

In SRC_lapwso/hmsec.F, line 4 has:

USE param

Line 771 has:

allocate (hso(num2))

In hmsec, it looks like the zhhevx call passes hso to variable AP that 
later gets passed to ABP.

In SRC_lapwso/modules.F:

MODULE param
INTEGER           :: num2=     0

Line 205 in SRC_lapwso/lapwso.F:

       num2= nume2*(nume2+1)/2+(nume2/hblock+1)*(hblock*(hblock-1)/2)

I'm not completely sure, but I wonder if the error is caused because in 
PROGRAM lapwso of lapwso.F there is not a line:

USE param
