Hi,

There was a bug reported against R, which was later tracked to be a bug in 
LAPACK. I have created a workaround patch. More details and steps to 
reproduce are in the R bug:
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15211
The patch is attached to the bug: 
https://bugs.r-project.org/bugzilla3/attachment.cgi?id=1478

In short, DLARRB() gets stuck in an infinite loop during computation of 
eigenvalues and eigenvectors of the particular matrix.

I am not familiar with LAPACK release and bug fix process, I am just an R 
user. I would appreciate if you take a look at the bug.
