<div> </div>
<div>I am quite new to wannier90 using it since november 2018 for my master thesis calculating tight-binding models but got along well with version 2.1.0. However I was exited when I realised that wannier90 in the latest version supports multithreading. But I ran into a problem as my calculation stopped with a segmentation fault error. Any idea why that occured? Below I simply pasted what my console was showing me when the program collapsed. I'm using wannier90 together with quantum-espresso.</div>
