Submitted: 2016-01-24 18:47 UTC Modified: 2016-01-24 18:52 UTC
From: bwoebi@php.net Assigned: bwoebi
Status: Closed Package: Reproducible crash
PHP Version: 7.0.3RC1 OS: Irrelevant
Private report: No CVE-ID:
 [2016-01-24 18:47 UTC] bwoebi@php.net
Description:
------------
Returns in try/finally in Generators with typehint modify the FAST_CALL opcode (which is next to VERIFY_RETURN), hence it crashes (or may behave strangely if executed).

Test script:
---------------
function (): \Generator {
        try {
                $foo = 1;
                return yield $foo;
        } finally {
                print "Ok\n";
        }
};


Expected result:
----------------
No crash / normal behavior
