Debian sid, PHP cli, xdebug, set_error_handler, mysql_list_dbs, throw = Segmentation fault

[Sven Uhlig <svenuhlig@web.de>]

Hello again,

this time I write to this list to report a bug, a segmentation fault.
Couldn't find any lead to this bug anywhere else. And because of so many
related packages, I dont know where to post it. Did I find the right place?

The following PHP code exits in "segmentation fault".

<?php
function error_handler() {
  throw new Exception;
}
set_error_handler('error_handler');
mysql_list_dbs();
?>

No segmentation fault if I do either of these things:
1) disable xdebug
2) don't set_error_handler
3) don't throw exception
4) throw exception after mysql_list_dbs but outside of error_handler

As I only wanted to use mysql_list_dbs() for testing purposes I don't
need an alternative solution. I know that this function is deprecated in
PHP5.4.

Some technical details:
$ strace php test.php 2>&1 |tail -n 3
read(3, "\7\0\0\2\0\0\0\2\0\0\0", 16384) = 11
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
