Well, quoting your cygcheck output:

Basically, this means that your /etc/passwd and /etc/group files aren't up
to date. Try updating them and re-running your command.
Also, your strace output isn't useful, primarily because you weren't
tracing the relevant parts of the command. You should have run
strace -o trace bash -c "cat <<EOF
foo
EOF"
This would have included the way bash resolves the "here document" in the
trace.
