    of course, mathtools loads amsmath, and gahter is not touched by mathtools

    it seems to be memoir interacting with something in amsmath

    Do not know what, yet.

i've confirmed that the first example
has the same effect with amsart, so it's
undoubtedly a problem in amsmath itself.
it's been put on our bugs list, but will
likely not be debugged (by us) real soon.
if anyone comes up with solid hints,
please send them to the attention of
  tech-support at ams.org
thanks.
