From: zaq178miami at gmail dot com Operating system: Debian GNU/Linux 8.2 (jessie) PHP version: master-Git-2016-01-29 (Git) Package: *General Issues Bug Type: Bug Bug description:Return typehint on interanal func causes Fatal error when it throws exception Description: ------------ In debug mode, when we define return type info as object and specify class for it, e.g. ZEND_BEGIN_ARG_WITH_RETURN_TYPE_INFO_EX(test_arginfo, ZEND_RETURN_VALUE, 0, IS_OBJECT, "ClassName", 0) ZEND_END_ARG_INFO() and then throw exception from function, e.g. PHP_FUNCTION(test) { if (zend_parse_parameters_none() == FAILURE) { return; } zend_throw_exception(zend_exception_get_default(), "Test exception", 0); } we have fatal error "Fatal error: Return value of test() must be an instance of ClassName, null returned in Unknown on line 0" While allow_null set to 1 fixes this problem, it is clearly a bug, while after exception thrown, method returned value not used, so no type check after exception should be performed (debug mode affected only). -- Edit bug report at https://bugs.php.net/bug.php?id=71485&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71485&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71485&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71485&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71485&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71485&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71485&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71485&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71485&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71485&r=support Expected behavior: https://bugs.php.net/fix.php?id=71485&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71485&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71485&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71485&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71485&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71485&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71485&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71485&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71485&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71485&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71485&r=mysqlcfg
