The change is **only** about EH_THROW handling. EH_THROW is used by extensions to replace warnings etc with exceptions. Currently the exception is thrown, but error_get_last() still behaves as if the warning was thrown instead. Fixing this does seem like a normal bug fix to me. Note that this does not touch exceptions thrown from error handlers or similar in any way. Basically the problem is that an extension using zend_throw_exception directly and an exception throwing through EH_THROW will behave differently, while there should be no difference. The part about behavior being dependent on whether you catch the exception or not: This is true only insofar as an uncaught exception generates a fatal error and that fatal error is retrievable through error_get_last(). There is no special casing occurring here. Nikita
