[Gmsh] OpenCASCADE wire or line loop with tag ** already exists

[Jean de sauvage]

Hello,

I have a problem with a .geo I've written automatically (I cannot change
tags manually). The code is reproduced below. It is a bit long but I do not
reproduce this error with smaller pieces of code !

I get the following error :

Error   : OpenCASCADE wire or line loop with tag 75 already exists
Error   : '/home/jds/Etudes/clouage/clouage_fusion.geo', line 117 : Could
not add line loop

And when I suppress the line defining Line Loop 75, I get an error saying
this LIne Loop does not exists.

I must I am a bit confused and if anyone had an idea about what be wrong
here, I would be thankful.

Sincerely, Jean
