[Gmsh] bug when re-loading a mesh

[GARNAUD Xavier (SAFRAN)]

Dear all,

I generated a mesh with the latest version of gmsh available via svn using a step model, and exported it as a msh file:
//-*- C++ -*-
// // Meshing algorithm
Mesh.Algorithm=5;
Mesh.Algorithm3D = 1;
Mesh.Optimize = 1;
Mesh.OptimizeNetgen = 1;

// Geom parameters
Geometry.OCCFixDegenerated = 0;
Geometry.OCCFixSmallEdges = 0;
Geometry.OCCFixSmallFaces = 0;
Geometry.OCCSewFaces = 0;
Geometry.OCCConnectFaces = 0;
Geometry.OCCScaling = 0.001;

// Import the step file
Merge "LS89_3Ddomain.step";

//Physical Groups
Physical Surface("inlet") = {1};
Physical Surface("outlet") = {3};
Physical Surface("top") = {2};
Physical Surface("bottom") = {4};
Physical Surface("front") = {7};
Physical Surface("back") = {6};
Physical Surface("blade") = {5};
Physical Volume("fluid") = {1};

Periodic Surface 2 {1,5,6,7} = 4 {3,11,9,12};
Periodic Surface 6 {4,7,10,12,15} = 7 {2,5,8,11,14};


When I try to reload it along with the CAD model, using a .go script like
// Geom parameters
Geometry.OCCFixDegenerated = 0;
Geometry.OCCFixSmallEdges = 0;
Geometry.OCCFixSmallFaces = 0;
Geometry.OCCSewFaces = 0;
Geometry.OCCConnectFaces = 0;
Geometry.OCCScaling = 0.001;

// Import the step file
Merge "LS89_3Ddomain.step";

Merge "LS89-mixed.msh";

I get:
terminate called without an active exception
Aborted

It works fine with version 2.12.0

Best regards

Xavier
