RHBA-2011:0442 - Bug Fix Advisory

Topic

Updated lapack packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

Description

LAPACK (Linear Algebra PACKage) is a standard library for numerical linear
algebra written in FORTRAN 77. It provides routines for solving systems of
simultaneous linear equations, least-squares solutions of linear systems of
equations, eigenvalue problems, and singular value problems.

This update fixes the following bug:

• Prior to this update, the "DLALSD" function incorrectly modified the value of

the "RCOND" argument. Consequent to this, an attempt to call this function with
a literal value such as "-1.D0" as the "RCOND" argument caused the calling
program to terminate unexpectedly with a segmentation fault. With this update, a
patch has been applied to prevent "DLALSD" from modifying the value of "RCOND",
and the use of a literal value no longer causes the program to crash.
(BZ#608039)

All users of lapack are advised to upgrade to these updated packages, which fix
this bug.
