[Pw_forum] pw2wannier90 in stand-alone mode ... Segmentation fault - invalid memory reference / more information

[plug at infim.ro]

Dear all

We managed to get some more information on this issue :

It seems that pw2wannier90-qe502.x tries to read from a memory address
which is not specified to it. This happens for  
`generate_guiding_functions` where ZDOTC runs : forms the dot product of
two complex vectors.

==21089== Thread 1:
==21089== Invalid read of size 4

Maybe this might help to find a cure.
