now here's the rub. from the glibc manual page:
...
int memcmp(const void *s1, const void *s2, size_t n);
DESCRIPTION
The memcmp() function compares the first n bytes (each interpreted as
unsigned char) of the memory areas s1 and s2. It returns an integer
less than, equal to, or greater than zero if s1 is found, respectively,
to be less than, to match, or be greater than s2.
RETURN VALUE
The memcmp() function returns an integer less than, equal to, or
greater than zero if the first n bytes of s1 is found, respectively, to
be less than, to match, or be greater than the first n bytes of s2.
...
this explicitly says that s1 and s2 have their BYTES compared... and
then returns just some value < 0, 0 or > 0 based on the difference. what
that value is and means is not defined, as long as it is < 0, 0 or > 0.
so the C standard has this to say:
6.3.1.3 Signed and unsigned integers
2. Otherwise, if the new type is unsigned, the value is converted by
repeatedly adding or subtracting one more than the maximum value that
can be represented in the new type until the value is in the range of
the new type.
so a result of -255 (possible) is converted by REPEATEDLY adding the
max size of the new type (255) until within range... so ...
-255 + 255 = 0 ... within range.. BUT FALSE!
so why do we see this now? something changed in memcpy behavior.
before we ONLY saw values of -1, 0 or 1 - nothing else, NOW we see
thins like:
-12288
49152
4096
16384
61440
-53248
so memcpy changed behavior, though within specs of the manual page
anyway, but now the values can be ones that break the simple assignment.

window at this point, so we cannot use it for comparison. Instead,
check the requested depth. Also fix best_depth_get function to not
return a hard-coded depth if a depth has been set already.

was using evas' window surface to do its resource creation and it
wans't properly updated when a window is destroyed and recreated.
Also, deleted some whitespaces.

position. Fix bug when clipping to viewport/framespace. These changes
fix Several buggers on Trac which related to the Wayland Engine(s).
Fix minor bug in evas_render where clipping for framespace would
not take into account the frame height and also move the frame clip to
the values specified in framespace (not viewport).
Fix buggers in evas_object_main which was causing objects (when created using
the wayland engines) to be an incorrect size & position (objects will now
be the same size/position in EFL Wayland as they are in X11).
Fix evas_object_geometry_get to return values based on where they were
moved (in relation to framespace). (These fixes are for the Wayland
Engines and do not affect X11).
Remove nw/nh from evas_object_resize (not needed variables anymore).

Used to just go for the first match in the cache which means it would always
think we only have the wrong size in the cache, and it would just add
new entries all the time.
