I'm pretty sure I tracked down this problem. In pmap.exp there is:
spawn $pmap -X 1
expect_pass $test "$pmap_initname\$"
and spawn is doing some things with stty and the pmap program's newline
characters are being converted to \r\n. The expect command is doing a
regular expression match looking for a newline and \r\n does not match
that. To make that pass, we need to do:
sed -i -r 's/(pmap_initname)\\\$/\1/' ./testsuite/pmap.test/pmap.exp
Use -r here instead of -e to avoid some extra baskslashes.
Another note is that the checks for procps-ng need almost all the
virtual file systems: /dev, /dev/pts, /proc, and /sys. The only one
that isn't needed here is /run/shm.
