[Help-glpk] bug ? Assertion failed: ap[q] != 0.0; file source/glpspx2.c; line 1249

[Sebastien . deMentendeHorne]

Hi,

I get a
Assertion failed: ap[q] != 0.0; file source/glpspx2.c; line 1249
when solving a small problem.

However, writing the mps and solving it with glpsol is ok.
I guess I can't reproduce it because I use LPX_K_DUAL = 1 (i.e. a basis of a
previous problem exists).

Is there a bug ? What can I send to make the discovery of the reason easier
?
Anyway, I send already the .mps and the ouput of lpx_print_sol (before
solving).
hope this helps making glpk better :-)

Sébastien
