Bug#774640: liblapack3: SVD throws error -4 in 3.5.0-4 while it runs with version 3.4.1.

[Madlene Nussbaum]

Package: liblapack3
Version: 3.5.0-4
Severity: normal

Dear Maintainer,

Some computations in R gave a matrix. The single value decomposition
of it worked fine previously, after an system upgrade I get the
following error in R:

-----
$ R
load("matrix-lapack-error4.RData")
La.svd(x,256,256)

 Error in La.svd(x, nu, nv) :
    BLAS/LAPACK routine 'DLASCL' gave error code -4
-----

Erroneous Matrix:
ftp://usys-ftp.ethz.ch/ITES/STEP/nussbaum/R/matrix-lapack-error4.RData
/.csv

* Previous version:     liblapack3   3.4.1 (running without error)
* New version:          liblapack3   3.5.0-4 (gives error above)
* Operation running without error using libopenblas-base or libatlas3-base


How do I track down this error code?
Is this a bug in liblapack3 or what did change?

Thank you for your help!
Madlene
