[Gmsh] Bug Report :Extrude to make spiral

[Jacques Kools]

Gentlemen,

first of all : congrats with GMSH and GetDP. I think it can look a  lot of commercial products straight in the eye !!

Second: I was trying to make a spiral by a combined translation/rotation extraction (geo file attached) and I found that the shape becomes quite funky. When I try to make a 3D mesh, it urges me to send a bug report.

I hope this is useful,

grtngs,

J.Kools
