You can use CVS to go back in time (cvs update -D date) until 
the problem disappear. This might be helpful in locating when the
problem originate, but don't assume that you will find why: since
nothing relevant about parallelization has changed with the last 
version, my guess is that your problem comes from incompatible 
libraries or from compiler bugs.
