Comment 18 for bug 1160569

On Linux, the glib slice allocator is disabled in |XREMain::XRE_main| by calling |g_slice_set_config| (see bug 431221). However, this no longer works since glib 2.35 because libgobject (which libxul depends on) now has a static initializer which indirectly initializes the slice allocator before |main| is reached (in order to automatically initialize the gobject dynamic type system). This means that the call to g_slice_set_config always fails with the following assertion:

(process:24722): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

See https://bugzilla.gnome.org/show_bug.cgi?id=687763

glib 2.35 is currently the version in Ubuntu 13.04
