LAPACK/ScaLAPACK Development

Dear LAPACK team,

(This is Debian bug #774640: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774640)

I crafted a minimal example of a suspicious error with DGESDD. The example can be downloaded from there:

• Fortran source: http://people.debian.org/~sebastien/bug774640.f90
• Matrix data: http://people.debian.org/~sebastien/bug774640.data

This example crashes in LAPACK 3.5.0 with the following message:

Code: Select all

 ** On entry to DLASCL parameter number  4 had an illegal value

I also tested current LAPACK version from SVN (r1594), and the problem seems to be still there.

However, the same program works well with LAPACK 3.4.1.

Cheers,
