I think this is a dup of bug 18932 and already fixed in 3.4.4.  (It was a latent bug).

(In reply to comment #3)
> Can you try 3.4.4?

There is no 3.4.4 on gcc.gnu.org.  Do you mean the head of the 3.4 branch?

No feedback in 3 months so assuming this is a dup of bug 18932.

*** This bug has been marked as a duplicate of 18932 ***
