Hi,

Are there some new thoughts about the issue? I don't think this email was
answered after it was sent a few months ago.

Hi Andrew,

How is the attempt to solving the bug I reported? I recently downloaded the
newest version of GLPK (4.65) and it is still crashing. If it was not
solved yet, could you please provide me with the fix you had sent at that
time?
Thanks!

Hi Andrew, all

The GLPK wikipedia and GLPK book now reflect the

GLPK 4.50 Release Information
*

Release date: May 24, 2013

GLPK (GNU Linear Programming Kit) is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems. It is a set of routines written in ANSI C89 and
organized as a callable library.

In this release:

A new version of LU-factorization routines were added.
Currently this version provides the same functionality as the
old one, however, the new version allows further improving.

Old routines for FHV-factorization used to update the basis
factorization were replaced by a new version conforming to the
new version of LU-factorization.

Some clarifications about using the name index routines were
added. Thanks to Xypron  for suggestion.

Some typos were corrected in the MathProg language reference.
Thanks to Jeffrey Kantor  for report.

A serious bug (out-of-range indexing error) was *tentatively*
fixed in the routine glp_relax4. Unfortunatly, this bug is
inherited from the original Fortran version of the RELAX-IV
code (for details please see ChangeLog), and since the code is
very intricate, the bug is still under investigation. Thanks to
Sylvain Fournier for bug report.

See GLPK web page at .

GLPK distribution can be ftp'ed from  or
from some mirror ftp sites; see .

GLPK is also available as a Debian GNU/Linux package. See its web page
at .
