The bug reproduces with PHP starting from version 7.1, but not before. Checked under different Linux versions Came into it when using PHP introspection functions on class with incorrect constants declaration. Don't know if the bug relates to this specific mistake or not. Test script: --------------- class SomeConstants {const SOME_CONSTANT = SOME_NONSENSE;} function handleError() {throw new ErrorException();} set_error_handler('handleError'); set_exception_handler('handleError'); $r = new \ReflectionClass(SomeConstants::class); $r->getConstants(); Expected result: ---------------- Fatal error: Uncaught exception 'ErrorException' in /code/1.php:10 Stack trace: #0 [internal function]: handleError(Object(ErrorException)) #1 {main} thrown in /code/1.php on line 10 Actual result: -------------- Segmentation fault (core dumped) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76536&edit=1
