Summary: constant() failed to check undefined constant and php
interpreter stoped
Status: Bogus
Type: Bug
Package: Reproducible crash
Operating System: Windows, Linux
PHP Version: 5.3.2
New Comment:
Hi Mike,
according to manual http://php.net/manual/en/function.constant.php
constant() eturns the value of the constant, or NULL if the constant is
not defined. And this happens with php 5.2 version. With php 5.3 there
is a fatal error and php interpreter stops. There are no words about
fatal error in manual.
