[Gmsh] [gmsh]: Fail to use CGNS I/O

[SOISMIER matthieu DSNA/CC]

Dear all,

I have successfully compiled gmsh with the cgns output support. Now, I 
am trying to use it, but it is not working :

|$ gmsh case.geo -2 -o case.cgns -format cgns
...
Info    : Done meshing 2D (0.543918 s)
Info    : 30693 vertices 49134 elements
Info    : Writing 'case.cgns'...
Warning : CGNS I/O is at an "alpha" software stage
Erreur de segmentation|

I run the commands 'gdb gmsh' and 'run case.geo -2 -o case.cgns -format 
cgns' to get the following trace :

|(gdb) backtrace
#0  0x0000003e9c078900 in strlen () from /lib64/libc.so.6

I looked into the source file 
|/home/msoismie/local/usr/gmsh-2.6.1-source/Geo/GModelIO_CGNS.cpp |in 
order to try to understand my mistake, but I did not find the |case 
write_CGNS_zones<2u>| (I have found only: |write_CGNS_zones<2>| and 
|write_CGNS_zones<3>|).

After reading the warning telling that 'the CGNS I/O is at an alpha 
software stage', I understand that the CGNS I/O has to be used 
carefully. Do you have any idea or suggestion that could help to solve 
this problem and allow me to use the CGNS I/O ?

Thank you in advance for your helpfull answers.

Best regards,
Matthieu Soismier
