Dear developers,

I am starting to use Wannier90 and ran into a segmentation fault problem.
After looking at the code, it is clear what is happening.

In /kslice.F90/, the code tries to use an array before it gets allocated.

The faulty line  is
/
//bnddataunit(n) = io_file_unit()//
/
It is interesting to note that /bnddataunit/ seems to not be used in the 
code.

Best regards,
Nicolas
