Subject: 26.1; c++-mode syntax highlighting after some symbols
Date: Sat, 5 Jan 2019 01:22:56 +0000
When I type symbols that start with the same characters as an operator 
alias
followed by an array subscript, the index is colored like a namespace if
it's a symbol as well.
Examples :

void a () {
   foo[bar]; // ok, foo doesn't start like an operator alias
   aor[bar]; // ok
   ora[1]; // starts with "or", but 1 is a number literal
   ora[bar][quux]; // bar is colored the same as std below, quux is fine
   std::sort;
}

int thing[bar]; // not colored
int nothing[bar]; // colored

struct A {
   int nanana[bar]; // not colored
   int andwhatever[bar]; // colored
};

I could reproduce this problem with Emacs 26.1, but not with Emacs 27.1,
so I guess this has been fixed by now, and I'm closing this bug report.
If there's more to be done here, please respond to the debbugs address
and we'll reopen.
