bup (in sysutils/bup) has lots of tests, and after recent improvements
bup's tests are hanging on NetBSD 10 amd64. I am almost certain this
is "new tests hang", not any kind of regression.
The new tests code is
#!/usr/bin/env bash
set -ueo pipefail
# Callers can test for support via "with-tty true".
usage() { echo 'Usage: with-tty command [arg ...]'; }
misuse() { usage 1>&2; exit 2; }
if script -qec true /dev/null; then
# linux flavor
script -qec "$(printf ' %q' "$@")" /dev/null
elif script -q /dev/null true; then
# bsd flavor
script -q /dev/null "$@"
else
rc=0
cmd="$(command -v script)" || rc=$?
if test "$rc" -eq 0; then
printf 'Unsupported script command: %q\n' "$cmd" 1>&2
else
echo 'No script command' 1>&2
fi
exit 2
fi
And I find after 15 minutes of hanging:

Attaching, I see:

which looks like an async-signal-safe botch leading to deadlock.
But, running script outside of bup works fine. (Bup does set
LD_LIBRARY_PATH to pick up bup-under-test libs.)
Any insight?
