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

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.
