gtk3: segfault on Darwin

[jbaum98]

Issue description

All programs that link to gtk+3 segfault when executed. This doesn't happen when the executable is linked to other non-nixpkgs versions of the gtk+3 library.

Steps to reproduce

// example.c
#include <gtk/gtk.h>

static void activate (GtkApplication* app, gpointer user_data) {
    GtkWidget *window;

    window = gtk_application_window_new (app);
    gtk_window_set_title (GTK_WINDOW (window), "Window");
    gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
    gtk_widget_show_all (window);
}

int main (int argc, char **argv) {
    GtkApplication *app;
    int status;

    app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
    g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
    status = g_application_run (G_APPLICATION (app), argc, argv);
    g_object_unref (app);

    return status;
}

# Makefile
example: example.c
	clang `pkg-config --cflags gtk+-3.0` -o $@ $< `pkg-config --libs gtk+-3.0`

install: example
	mkdir -p $(out)
	cp example $(out)

{ nixpkgs ? import <nixpkgs> {} }:
let
  inherit (nixpkgs.pkgs) gtk3;
  inherit (nixpkgs.pkgs) pkgconfig;
  inherit (nixpkgs) stdenv;
in
stdenv.mkDerivation {
  name = "gtk-test";
  src = ./.;

  buildInputs = [ gtk3 pkgconfig ];
}

Building it with just make using pkg-config and gtk+3 from Homebrew, the compiled executable runs and produces a blank window. Building with nix-build and running the compiled executable produces a segfault with the following backtrace.

You can try to export DYLD_FRAMEWORK_PATH=/System/Library/Frameworks before running the executable. See #12346.

I'm pretty sure this case is also fixed by #22571, but I run into this now with the example.

(example:55230): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.

Yup this is fixed by #22571. Thanks!
