Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

lets have a better backtrace (we need to see more than just the top
frame), and a short, self-contained reproducing script.

4.3.1 Source works fine.
4.3.2RC1 and latest CVS Snap produce the above

What is wrong?
