Description:
------------
PHP compiled without debugging symbols would crash while executing the
attached code.

If I recompile PHP with --enable-debug, it runs fine.


Reproduce code:
---------------
<?php
$f = 'var_dump';

function myFunc(){
  throw new Exception();
}

try {
  $f(myFunc());
} catch ( Exception $e ) {
  echo 'Exception', PHP_EOL;
}

try {
  $f(myFunc());
} catch ( Exception $e ) {
  echo 'Exception', PHP_EOL;
}

Expected result:
----------------
Exception
Exception

Actual result:
--------------
Exception
Segmentation fault
