1.79.1. RHBA-2011:0442: lapack bug fix update
Updated lapack packages that fix one bug are now available for Red Hat Enterprise Linux 5.
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.
* 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.
