I have GDB 8.0, so it should work well, right? It appears, though, that there are fewer buttons in the debug toolbar when the debugger is started with gdb than when it is started with gud-gdb.

Eli, which function is the entry point for the bidi module? Where should I set a breakpoint for starters?

They invoke 2 different interfaces between Emacs and GDB.  Depending
on what version of GDB you have there, "M-x gdb" might not be the best
choice, because it needs GDB 7.0 or later.

There's also this comment in gdb-mi.el, which is what "M-x gdb" uses:

  ;;; macOS:

  ;; GDB in Emacs on macOS works best with FSF GDB as Apple have made
  ;; some changes to the version that they include as part of macOS.
  ;; This requires GDB version 7.0 or later as earlier versions do not
  ;; compile on macOS.
