[Wannier] Segmentation fault in postw90.x

[Giovanni Pizzi]

Thanks for the report!
I just created a PR to fix this: https://github.com/wannier-developers/wannier90/pull/290

If all tests pass (as they should) this will get merged and be available in the next minor release of W90.

Thanks,
Giovanni

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
