[Lapack] lapack bug: is anybody listening

Sorry for not getting back to you earlier. 
We indeed corrected the bug you found, thank you for the patch. It is released 
in LAPACK 3.3.0 (released this week).
This bug was labelled bug0064.
If you could confirm that this issue is fixed, I will add a post on the forum 
to let the users know.

Please allow me to say how much I use and appreciate lapack.  It makes my

experiencing a bug related to least squares solution via singular value

no response on the lapack user's forum from the lapack maintainers.

Please see:

for a description of the bug, conditions to reproduce it, and a fix.  I would 
greatly appreciate it if this fix made its way into lapack!

Thanks and regards,
