Segfault in HEAD View as Markdown

Hi, after a cvs update i get a segfault with this script:
[...]

This sourcecode (which is the same except that there is no code in the
destructor) prints out:

Fatal error: Exception thrown without a stack frame in Unknown on line 0

-- snip --
<?php
class test {
function __destruct() {
}
public function start() {
throw new Exception();
}
}

$test = new test();
$test->start();
?>
-- snip --

From zend_exceptions.c:

if (!EG(current_execute_data)) {
zend_error(E_ERROR, "Exception thrown without a stack frame");
}

This might help tracking down the problem.

/ Timm

This should be fixed now. Thanks for the short reproducing script.
