A few problems here… The newly built debugger (macOS High Sierra, version 10.13, obviously comes without one) needs to be "codesigned". This does not work here as in theory, practically. Maybe I need to reboot, disable that "gatekeeper" completely, or whatever. Is maybe root allowed to use GDB instantly?
The easiest step was to build two Emacsen with different levels of debug information.
BTW, GDB and I cannot find the text set_locale, except here:
../src/xterm.c: /* gtk_init does set_locale. Fix locale before and after. */
I am using the athena variant with Xaw3d.
Try using LLDB instead of GDB, it works better on macOS and doesn't require codesigning.
