This (mis)behavior is consistent with DWB 3.3 and Heirloom Doctools mm.

Bug #56499 also documents a case where a new trap can erroneously overwrite a nearby end-of-page trap despite being at a different page position.  Could that bug's trap behavior be the root cause of this bug?

[Mike Bianchi asked (http://lists.gnu.org/archive/html/groff/2021-02/msg00077.html) who maintains the mm macros, implying it's not him (although he didn't respond to a direct query about this (http://lists.gnu.org/archive/html/groff/2021-04/msg00019.html)).  Thus I'm unassigning this mm bug.]

GROFF VERSION:  1.18.1

MACHINE:  IBM-compatible Pentium IV

OS:  Linux 2.6.21.5 (Debian Etch or Sid)

COMPILER:  none (using Debian package)

INPUT FILES:  foo.tr (attached)

COMMAND LINE:  groff -mm foo.tr    # using groff version of mm

DESCRIPTION OF INCORRECT BEHAVIOUR:
The footnote reference occurs with exactly enough space
remaining on the page for the footnote.  The end-of-page
trap is apparently clobbered; text continues over the page
boundary and the footnote appears on the next page.  As
expected, if the footnote-reference line is moved one unit
higher or lower, it works properly with the footnote
appearing on the same or next page, respectively.
