Dear Quantum ESPRESSO Community

I have tried to run the diamond example from
espresso-5.2.1/PP/examples/WAN90_example
using Wannier90-2.0.1 and QE 5.0.2.
pw2wannier is compiled in stand-alone mode with QE 5.0.2.

After running the example I get the message :

 <== Stand-alone Mode ==>
  running wannier90 -pp for diamond... done
  running pw2wannier90 in stand-alone mode for diamond...
Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

The scf and nscf calculations are alright. Any suggestions, please ?
Thanking you,
Neculai
