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

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

Erroneous Matrix:

* 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!
