Yes, GDB's "b backtrace_function" command says: Breakpoint 1 at 0x6e4b7: backtrace_function. (10 locations) which suggests that at least one of the breakpoints will work. However, Emacs developers need GDB to cause the debugged Emacs process to call backtrace_function, and that doesn't work (Emacs crashes) due to the GDB bug.
