I think a appropriate way to fix these issues(memleak, xdebug, this issue) is
catch->efree->throw. I have made a patch.
Derick, what do you think?

Checking SVN history revealed r322922 as the cause - see http://svn.php.net/viewvc?view=revision&revision=322922.
Reverting it fixes this bug.
The commit mentions a relation to bug #60218 but I'm not sure why it "Reinstated correct
return values". Before this fix the code in zend_execute_API.c read:
zend_execute(new_op_array TSRMLS_CC);
[...]
retval = SUCCESS;
After the fix it read:
zend_try {
zend_execute(new_op_array TSRMLS_CC);
} zend_end_try();
[...]
retval = SUCCESS;
Finally, r322922 changed it to:
retval = SUCCESS;
zend_try {
zend_execute(new_op_array TSRMLS_CC);
} zend_catch {
retval = FAILURE;
} zend_end_try();
The zend_catch "block" is executed whenever SETJMP returns non-zero, so basically when
LONGJMP is called, which is the case for zend_bailout(), which again is used by exit() and die(). To
my eyes, this *changed* the return value instead of reinstating it.
@derick, maybe you can shed some light on this commit?

Test suite:
<?php
if (!isset($argv[1])) {
exit("*** Usage: php exit.php /path/to/php/binary\n");
}
$php= realpath($argv[1]);
if (!is_executable($php)) {
exit("*** PHP Binary '$argv[1]' is not executable\n");
}
$tests= array(
"echo '';" => 0,
"exit('test');" => 0,
"exit(2);" => 2,
"fatal();" => 255,
"\$->" => 254,
"throw new Exception('test');" => 255
);
foreach ($tests as $source => $expected) {
$cmd= '"'.$php.'" -r "'.$source.'"
2>&1';
$output= array();
exec($cmd, $output, $actual);
if ($actual === $expected) {
printf("%-30s: [OK]\n", $source);
} else {
printf("%-30s: [FAIL, expect %d, have %d (%s)]\n", $source, $expected, $actual,
implode(' ', $output));
}
}
?>
