If the below script is run, it returns a completely blank page. If a non-erred script is then run, the non-erred script also returns a blank page. It's only fixed by killing the offending child process. With output buffering disabled, everything works as expected and the child process doesn't need to be killed. Test script: --------------- <?php echo "Working happily"; call_nonexistent_function(); ?> Expected result: ---------------- Working happily FATAL ERROR: Call to undefined function call_nonexistent_function() in..... Actual result: -------------- Blank page - nothing at all. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64956&edit=1
