Direct access to php constants breaking smarty

Hi,

We upgraded from Smarty 3.1.21 to 3.1.33

Apparently, if you have a php variable defined as follows :

define("myvar", "My var value");

It can be accessed in the template as {myvar}

Can we stop this behavior ?

In our app we have a php constant defined named "assign" which breaks the smarty template when the assign tag is used.

There should be a way to not directly "see" these keywords as constants since anyone can break smarty by defining a php variable having the same smarty tag name. And btw the generated exception doesn't say much, it was hard to find.

Thanks !

Start by reproducing the reported behavior with a PHP constant named "assign" and a Smarty template using the assign tag, comparing Smarty 3.1.21 and 3.1.33 if possible. Trace how template identifiers are resolved as PHP constants and inspect the generated exception. Done means constants no longer unexpectedly shadow Smarty tags and the resulting error is informative.
