      The following snippet breaks C syntax highlight for me. I'm using VIM 7.3.495

      #define GDBUS_ARGS_INFO(args...) (const GDBusArgInfo[]) { args, { } }



      static const GDBusMethodTable char_methods[] = {
      {
      "GetProperties", "", "a{sv}", get_properties,
      .out_args = GDBUS_ARGS_INFO({ "properties", "a{sv}" })
      },
      { }
      };


      If i change the "}" inside the string to \7xd, the problem disappears.
      It appears that the problem is related to the open parenthesis and the
      close bracket. If I use anything that do not open a parenthesis, then
      it's back working.

      Is there a way to properly fix this in c.vim?

      Regards,

      ... Hmm, there are some weird dependencies with extend and keepend. Try the c.vim file below. It might introduce new problems though. Vim syntax file

        Hmm, there are some weird dependencies with extend and keepend. Try the
