PR 37739 applies to 4.3.3, as does the fix (applied by hand to my sources). I'm running "make check" right now with the patched sources.
The test suite has finished (I only built the C compiler), and results are at http://gcc.gnu.org/ml/gcc-testresults/2009-02/msg01220.html
4.3.x is no longer supported so just closing as a dup of bug 37739. *** This bug has been marked as a duplicate of bug 37739 ***
