PHP Bug Type: Reproducible crash
Bug description: throw Exception in error handler causes crash
Description:
------------
When I using Phing, My testcase with PEAR-SOAP and rdfapi-php had stopped
with segmentation fault.
And I Found that throwing exception in error_handler causes Seg fault.
Reproduce code:
---------------
<?php
set_error_handler('errorHandler', E_USER_ERROR);
try{
test();
}catch(Exception $e){
}
restore_error_handler();
function test(){
trigger_error("error", E_USER_ERROR);
}
function errorHandler($errno, $errstr, $errfile, $errline) {
throw new Exception();
}
?>
-----
no try and catch
<?php
set_error_handler('errorHandler', E_USER_ERROR);
test();
restore_error_handler();
function test(){
trigger_error("error", E_USER_ERROR);
}
function errorHandler($errno, $errstr, $errfile, $errline) {
throw new Exception();
}
?>
Expected result:
----------------
nothing
Actual result:
--------------
