New Comment:
Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
Can't reproduce it on Linux with latest CVS of 5.0 & 5.1 without
debug.
Make sure that you're trying the right binary.

Tested with the latest snapshot (200505110630) on Windows XP, and it is
still crashing.

Runs in php 5.1 now.

The first problem here is that the negative key results in incomplete
initialized zvals internally *before* even calling offsetSet().

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:
php5ts.dll!shutdown_memory_manager(int silent=0, int full_shutdown=0,
void * * * tsrm_ls=0x00364b38) Line 490 + 0xb C
