Summary:                    expressions are not working
Description: 
In Asterisk 1.4.23.1, expressions don't seem to be working.

According to the docs (doc/channelvariables.txt),  you should be able to
do this:

exten => 1,2,Set(koko=$[2 * ${lala}])
        

In my system I have this:

exten => i,2,Set(TRIES=$[1 + ${TRIES}])

However, it generates this error:

 WARNING[6389]: ast_expr2.fl:407 ast_yyerror: ast_yyerror():  syntax
error: syntax error, unexpected $end, expecting '-' or '!' or '(' or
'<token>'; Input:
1 + 
    ^

I also reversed it:

exten => i,2,Set(TRIES=$[${TRIES} + 1])

But it still didn't work.

I know this worked in the past so is there something I'm not seeing or
are expressions not working in Asterisk?
