Subject: [Q-e-developers] Problem with bcasting unallocated arrays in pw2wannier (5.1)<br>

Hi!<br>
<br>
PP/src/pw2wannier90.f90 is broadcasting spin_eig and spin_qaxis even<br>
when they are not allocated. This causes crashes with at least gcc 4.6 +<br>
Impi 4.1.3, msglen = size(msg) in mp_bcast_iv gets set to 1 in some<br>
cases. I'm assuming this is a compiler bug, but it's still better not to<br>
bcast them in this case.<br>
<br>
Patch attached.<br>
