Summary: call to GLPK hangs

Details:
The following sequence of calls to glpk to solve a small (8x48) linear
programming problem hangs:
epun:/tmp> octave
octave-3.2.3:1> global A b c
octave-3.2.3:2> load "Abc.out"; # file Abc.out is attached.
octave-3.2.3:3> [y, fmin, status, extra] = glpk( c, A, b )
(no output)
I am using GNU Octave, version 3.2.3, (binary file downloaded from
octave.sourceforge.net)
The present bug is very sensitive to the matrices A, b and c's values. If I
were to store the variables in ascii format (instead of binary) the bug
vanishes. I am guessing this is because of truncation.
This may be a GLPK bug and not an octave bug after all. If so, how can I
tell?
Many thanks,
Mahesh
