spcomp assertion on malformed if

Headline commented 5 years ago

thanks to shavit for reporting this one.

Gave it a shot myself, but a solution wasn't obvious to me. Here's how to replicate

int main(){
    if(
    {
        int b = c();
    }
}

Oh gross.

The bug is that { begins an array expression, but those are only expected within initializers.
