WRT gtk3, the culprit was actually an apparent LTO bug in 
libcairo-gobject (a thin GObject wrapper for libcairo which gtk2.0 does 
not use); any call to CAIRO_GOBJECT_TYPE_* seems to go to la-la land and 
SEGV.  Recompiling libcairo-gobject without -flto allows gtk3 to work. 
(Strangely enough, the much larger libcairo itself seems to work even 
with -flto.)  As for fixing LTO, well, that will have to be a different 
discussion; at least we can move forward again with the GNOME stack.
