[Lapack] Bugfix for inclusion in upstream version

[Sven Hammarling]

Dear Wolfgang,

I promise you that we do appreciate your bug report and it will, I am 
sure, be investigated.

Please realise that most of us do this on a voluntary basis and cannot 
always reply quickly, that does NOT mean that we are not interested. 
This week in particular many of the LAPACK/ScaLAPACK people will be in 
Reno at SC07.

With best wishes,

Sven Hammarling.
