[Gmsh] A bug is found in meshing information!

Hello!
 
I have  found a bug in meshing information.
I found the tetrahedra element counter was wrong.
There are actully 102 tetrahedra elements generted while the statistics given in meshing process gave us 101 (see below).
I call gmsh program in Matlab and use the element and node information for analysis. 
I found that the meshing information given by gmsh in counting. See the attached file test1.msh. There are 102 tetrahedra elements generated subtantiilly from 117 to 218.
218-117+1 = 102. But the statistics informatio gave us 101.
The .gmsh and .geo file is attached in this mail.

EFG3DAnalysis(gmsh_file_name, test_model)  //that is the matlab command line
eval(strcat('!','F:\gmsh-2.0.8-Windows\gmsh',gmsh_file_name,' -3')); //that is the matlab command line
