Are you sure there is a cycle?
Rest_collision does use the height of the rests to determine the
height of the
rests, but I do not see where calling the Rest::height() function can
call
Rest_collision() cyclically.
Is there some LilyPond input that causes infinite recursion or gives
the error
message from the trap for cyclic dependencies ?
In master there is no message because of the way Rest::height works. It
gets a stencil for the rest without actually calling
get_property("stencil"), which means there is no record that the stencil
is already being calculated at the time Rest_collision asks for the
extent of the rest, which asks for the stencil, which is being
calculated.
I discovered this when I tried to use get_property("stencil") from
Rest::height while trying to fix issue 4245.
