Please see if you can reproduce this in an unoptimized build.  The
backtrace you sent indicates this was an assertion violation here:

      eassert (EQ (XFRAME (selected_frame)->selected_window, selected_window));

but I distrust backtraces from optimized builds.  That said, can you
show the values of XFRAME (selected_frame)->selected_window and of
selected_window, together with the details of each of these 2 window
objects?

Also, can you try recollecting what were you doing when this happened,
and perhaps show the contents of the recent_keys vector?

For the record, which version of GCC was used for building this
binary?

Thanks.
