<p>SIGSEGV errors can have many possible causes [

].</p>
<p>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 [

].</p>
<p>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 [

Please tell me how to rectify this problem. For cubic

problem occurred. <br>
