Could be Clang is *not* the proper compiler…

Of course code signing does not work after a reboot (bug report with Apple opened), so I used the root account for debugging. I started GDB 8.0.1 (installed as '-rwxr-xr-x  1 root  admin  6248012 17 Nov  2017 /opt/local/bin/ggdb') à la


	env LC_NUMERIC=de_DE.UTF-8 ggdb -i=mi emacs-27.0.50.1

Communication with GDB is:

...
	SIGINT is used by the debugger.
	Are you sure you want to change it? (y or n) [answered Y; input not from terminal]
	DISPLAY = :0
	TERM = dumb
	(gdb) set args -Q
	(gdb) break setlocale
	Function "setlocale" not defined.
	Breakpoint 3 (setlocale) pending.
	(gdb) run
	Starting program: /Users/pete/Quellen/Emacs_CVS/emacs-27.0.50/src/emacs-27.0.50.1 -Q

Launched Emacs displays the error, but gdb does show any prompt. In the window *breakpopints of ...* is shown:

	Num Type       Disp Enb Addr               Hits What
	1   breakpoint keep y   0x000000010024a360 0    <terminate_due_to_signal>
	2   breakpoint del  y   0x00000001002928e0 0    <init_sys_modes>
	3   breakpoint keep y   <PENDING>          0    setlocale

I'll try anew with GCC!
