[Help-glpk] Infinite loop in glplx6a.c

[Sebastien . deMentendeHorne]

I have a problem when calling lpx_simplex(lp).
It loops infinitely on some data sets in the function lpx_simplex with the
path:
L1360 in glplx6a.c    feas:
                                ret = LPX_OK
                                goto opt
                                ...
L1392 in glplx6a.c    opt:
                                ret = LPX_E_INSTAB
                                goto feas 
Hence, it oscillates between the first step (find a feasible primal
solution) and the second (find an optimal basis solution).

Is it possible ? Is it a bug ?
