I looked briefly at this (don't have time to dig further right now).
It seems that the problem is that in redisplay_internal, the frame title is
drawn _before_ the windows are updated, so the stuff which depends on
actual window contents (such as %l) may fail to render properly -- and
even crash emacs as we have seen here.
Perhaps a simple fix would be to move the call to x_consider_frame_title
currently inside prepare_menu_bars to after we have completed the
window updates...
Unfortunately, this comment says this is not TRT ... so what is TRT?
/* Update all frame titles based on their buffer names, etc. We do
this before the menu bars so that the buffer-menu will show the
up-to-date frame titles. */
BTW, what does frame titles have to do with the buffer menu?
