Bug description: Segfault when offsetSet throws an Exception (only without
debug)
Description:
------------
In some cases, when offsetSet throws an exception a segfault occurs.
This does not happen when compiled with --enable-debug.
Note that if the index passed to $list is positive or a string, not
segfault occurs.
Reproduce code:
---------------
class a implements ArrayAccess
{
function offsetExists ($offset) { return false; }
function offsetGet ($offset) { return null; }
function offsetSet ($offset, $value) { throw new Exception ("Ooops"); }
function offsetUnset ($offset) {}
}
function test()
{
$list = new a();
try {
$list[-1] = 123;
} catch (Exception $e) { }
return true;
}
print test();
Expected result:
----------------
The output should be "1".
Actual result:
--------------
Segmentation fault.
The stack trace reported in Visual Studio, using the latest snapshot and
debug pack is:
