[Gmsh] Gmsh crash

[Martin Kraska]

Hi, 

when I try to create a compound surface in gmsh 2.13.0-svn-linux 64, I get this error:

Error : Unknown surface 23 
Warning : Could not make generatrices list for compound surface 30 

When I try to mesh this, gmsh crashes. Without the compound surface I can mesh the part without problems, see

What can I do to properly create a compound surface? 

Best regards, Martin Kraska
