Undefined variables

[Stadly]

Consider the following smarty template.

{"{if false}"|cat:{'foo'}|cat:"{/if}"}

It is compiled into the following php template.

ob_start();
if (false) {
$_prefixVariable1=ob_get_clean();
ob_start();
echo 'foo';
$_prefixVariable2=ob_get_clean();
ob_start();
}
$_prefixVariable3=ob_get_clean();
echo (($_prefixVariable1).($_prefixVariable2)).($_prefixVariable3);
}

When the compiled template is run, it generates two errors: Notice: Undefined variable: _prefixVariable1 and Notice: Undefined variable: _prefixVariable2.

Note: Obviously, the template is not very useful, since I've tried to make a minimal example to show the issue. But I ran into the issue when using some similar logic in a template that was actually useful.

The master branch has been updated to throw a compiler exception for this condition.
