While I agree that it's worth trying a bisection -- it's generally really quick
and easy to do (the compiler and libraries build rather fast -- about a minute
for me).  It can be a very useful technique for finding where bugs were introduced.

That said, it's likely to be rather difficult for this release due to the number
of fixes in the compiler that the library requires and for the periods during
which the two didn't work together.

Do try it.. worst case is you've wasted a little bit of time.  Best case you've
found the cause of the bug.

Later,
Brad
