Memory Leak in ob_get_clean() / ob_get_flush ()

Hi, When running 'make test' on my system I discovered that tests/output/ob_start_basic_unerasable_003.phpt and tests/output/ob_start_basic_unerasable_004.phpt produced memory leaks - due to the fact that they first fetch the buffer into return_value but then do RETURN_FALSE if they detect an error and thus leak the copied buffer. I attached a patch that fixes that to this mail. Any objections to me applying this for 5.3 and HEAD? (after 5.3 RC1 when commits are allowed again of course) Any side-effects I didn't think about? Regards, Christian
