Hello.
For reference | Execute 'man ' e.g 'man alias'; this opens a
BASH_BUILTINS(1) titled manual. The obvious is then noticeable: a manual
entry for bash_builtins does exist. Once it is searched with 'man', it is
no longer found.
To reproduce:
$ man bash_builtins
No manual entry for

requested with the -t option) in all cases.

See the comment in doc/builtins.1:

No, they probably have a /usr/share/man/man1/alias.1.gz -> bash-builtins.1.gz
symlink or something, set up by their OS vendor.
We do not. Because we're

Thanks for the report. It's an easy fix.

It also appears to reset the EXIT trap in an interactive shell.
unicorn:~$ shopt -s execfail
unicorn:~$ trap 'echo
If execfail is set, a failed exec does not cause a non-interactive shell to
exit, but it seems to reset the EXIT trap:
cat <<'EOF' | bash
shopt -s execfail
trap "echo exiting..." EXIT
exec ~/does-not-exist
echo "exec failed in bash-$BASH_VERSION"
exit 1
EOF
Output:
bash: line 3:

man bash(1) says the following for the execfail option:
execfail
If set, a non-interactive shell will not exit if it can‐
not execute the file specified as an argument to the
exec builtin
