[MOAB-dev] Possible bug in moab::Core::get_coords

[Roman Putanowicz]

Dear All, 

The same program, same data, two different machines and two different outputs.
Could someone of you, please, confirm the results so I can exclude
some stupid configuration bug (like wrong lib version though I have checked
that :)

In the attachment there is a simple program and data file.
The program finds the length of a perimeter of a skin of a triangle mesh.

I run it on two machines:

machne A:
gcc --version : gcc (Debian 4.4.4-6) 4.4.4
uname -srm    : Linux 2.6.32-trunk-686 i686

machine B: 
gcc --version : gcc (Debian 4.3.2-1.1) 4.3.2
uname -srm    : Linux 2.6.26-2-amd64 x86_64

MOAB svn version 4070

Running the program I got:

   Machine A:        |            Machine B        
---------------------+---------------------------
V: 1 2               |          V: 1 2
0 0 0 1 0 0          |          0 0 0 1 0 0 
V: 2 3               |          V: 2 3
1 0 0 1 1 0          |          1 0 0 1 1 0 
V: 3 4               |          V: 3 4
1 1 0 0 1 0          |          1 1 0 0 1 0 
V: 1 4               |          V: 1 4
0 1 0 0 1 0          |          0 0 0 0 1 0         <<--------- BINGO 
Perim length: 3      |          Perim length: 4

For the test data (unit square mesh) correct anser is of course B.

( BTW why the vertices of the last edge are 1 4 and not 4 1 ? )

Compiling the program 
g++ -I INC_PATH -L LIB_PATH coordsBug.cxx -lMOAB -o coordsBug

Running:
coordsBug two_triangles.vtk

Thanks in advance for any hint.

Regards,

Roman
