OK, here we go for a shorter crasher:
<?php
class Thing {}
function boom()
{
$reader = xml_parser_create();
xml_set_object($reader, new Thing());
die("here");
xml_parser_free($reader);
}
boom();
?>
Some comments on the environment:
- crashes with CLI (that could be useful to speed up testing
and avoid crashing your company's internet web server)
- Doesn't crash with the default Tiger PHP (4.3.11)
- Doesn't crash with my modification (freing the store after
resources). That said, it was a quick fix, and I don't know
the Zend engine sufficently to ensure it is safe in other
situations.
Some comments on the crasher:
- dying() after the xml_parser_free doesn't crash anymore
(the parser has been manually freed, so that's the same as
freing resources before the objects_store).
- the code must be in a function to crash.

Yet another chicken-and-egg problem with resources and objects.
xml_parser uses object for callbacks that is already destroyed at the
time when the resource is being destroyed.

Same exact problem with 5.1.0RC2-dev (only line numbers in the
backtrace differ).
