If you use recent Lapack, it should be OK according to :

http://www.netlib.org/lapack/lapack-3.1.0.changes

"
================
== LAPACK 3.1 ==
================

Release date: Su 11/12/2006.


"6) Thread safety: Removed all the SAVE and DATA statements (or provided
     alternate routines without those statements), increasing reliability
     on SMPs."

Also, from this pdf file,

http://www.lahey.com/docs/blaseman_Lin62.pdf

I see:

"This manual describes the usage of the following two software.
BLAS thread-safe version V4.0
LAPACK thread-safe version V4.0

Example program using thread-safe subroutines
This section shows an example code that uses subroutines
from BLAS and LAPACK thread-safe
versions. The example is simple enough to understand
and intended for use in order to describe
principles of calling thread-safe subroutines from an
OpenMP Fortran program.
"

So, It seems from all the above and few other things I've
seen googling this, that current versions are thread safe.
