With a 50-MB limit, I see this failure on x86_64:

  + echo 'AM_CONDITIONAL([C24], [:])'
  + aclocal-1.11a -Werror
  + automake-1.11a --foreign -Werror -Wall
  Out of memory!
  Out of memory!
  + exit_status=1
  + set +e
  + cd /h/j/w/co/automake/tests
  + test no = yes
  + case $am_explicit_skips in
  + test 1 -eq 0
  + keep_testdirs=yes
  + am_keeping_testdirs
  + case $keep_testdirs in
  + return 0
  + set +x
  cond29: exit 1

Same with 60MB, but it passes with 70MB.
So I suggest changing s/50/70/ in both the patch and the log message.
Maybe even 90 or 100, just to be a little more future/bloat-proof.
