don't know if it is related , but I opened a PHP bug due to other issue
with
SplTempFileObject (xdebug unloaded)

http://bugs.php.net/bug.php?id=37257

fixed the mentioned PHP bug, I recompiled PHP. and **without** xdebug it
works as expected now.

but stills segfaults with xdebug loaded. :-(

Fixed in CVS. The cause was that Xdebug didn't understand the EH_THROW
error mode yet.
