It appears that the seg fault doesn't appear in debug builds.
Recompiled without debug again, and the seg fault is still present

No APC or XDebug.
Will recompile with debug and get a bt.

I could not reproduce it in Mac OS X
do you use any extension like apc, xdebug?

Description:
------------
Calling an undefined method in a generator results in an expected fatal error,
but then a segmentation fault occurs afterwards.
Test script:
---------------
function gen($o)
{
yield 'foo';
$o->fatalError();
}
foreach(gen(new stdClass()) as $value)
echo $value, "\n";
Expected result:
----------------
foo
PHP Fatal error: Call to undefined method stdClass::fatalError() in
/home/jared/fatalSegFault.php on line 6
Fatal error: Call to undefined method stdClass::fatalError() in
/home/jared/fatalSegFault.php on line 6
Actual result:
--------------
foo
PHP Fatal error: Call to undefined method stdClass::fatalError() in
/home/jared/fatalSegFault.php on line 6
Fatal error: Call to undefined method stdClass::fatalError() in
/home/jared/fatalSegFault.php on line 6
Segmentation fault
