[Gmsh] Bug report in gmsh 2.4.2

[David Colignon]

Hi Patrick,

with length = 0.0015 I am sable to generate a mesh with 161874 triangles on my Macbook with 2 GB of RAM, and with 
length=0.001 I get 369154 triangles ! With such a dense mesh, we are close to the machine precision and some random 
errors can occur. Could you try again with different values of length ?

Cheers,

Dave
