[Wien] problem while running "x w2w" command

[Gavin Abo]

SIGSEGV errors can have many possible causes [

].

In your case, I see W_14.2 below.  So perhaps it is due to a bug in an 
the older WIEN2k 14.2 or wien2wannier version that you are using.  You 
might try the newer wien2wannier version in WIEN2k 17.1.  However, you 
have to patch it [

].

What ifort compiler version are you using?  If it is a 2016 and 2017, 
maybe it is caused by the IO problem with large files [
