[Gmsh] Problem with periodic boundary condition for a volume extruded using wire

Dear Sir, 

I have a problem with periodic boundary condition. 

The model concerns a helix obtained by extuding using wire under OpenCASCADE Kernel (because in my final application, I need to use Boolean operation). 

Gmsh failed to apply periodic boundary condition with correct affine transform matrix of translation-rotation 

Please find attached the helix.geo files with a lot of comments which give a better explanation of my problem. 

Thanks for your clarification.
