[Gmsh] optimization hangs

[Giuseppe Borzì]

I think I have found a bug in gmsh, version 1.57.0 and 1.58.0. Open the 
file wg1.geo (a ridged waveguide), mesh it and then click on the 
"Optimize quality" button, it starts what seems to be a neverending 
optimization. At least on my AMD Athlon(tm) XP 1800+ I had to stop it 
when I saw the following line in top
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
15074 gborzi    25   0  127m 107m  25m R 95.8 10.6   7030:41 gmsh
Hope this helps.

Regards
