1.28 unbalanced '}'

[Tagunov Anthony]

Hello, friends!

I've hit a very frustrationg behaviour of bison 1.28 on Linux RH 6.1
I send the srouce file.
I compile it with 
bison  ces.y
and get what I've attached as a second file.

Here's an example of problematic output code

#line 37 "ces.y"
{ context->trace("description"); context->traceln(yyvsp[0]);;
    break;}
}

The curly brackets are unballanced!!

Will apprisiate your attention, best regards
