Why are the 32- and 64-bit cygwin1.dlls incompatible?

I just tried this snapshot:
and my 'ls' test succeeded.
Alas, my Orpie test failed:
$ PATH=/cygdrive/c/cygwin32/lib/lapack /cygdrive/c/cygwin32/bin/orpie
Fatal error: exception Assert_failure("main.ml", 30, 3)
Line 30 of main.ml is:
assert (cbreak ());
So....ncurses isn't working correctly across the exec() boundary?

Oh, it probably will, but a cygcheck dump will tell us when this is
probably happening, because both Cygwin bins will be in the PATH.
I'm hoping this new behavior will simply serve to let more people move
to Cygwin 64 before absolutely everything is ported.
To my mind, the biggest negative consequence of this improvement is that
it might delay the porting of some packages by removing an incentive.
