In bash 3.2, the [[ ]] quoting rules changed slightly. Since [[ already
introduces special quoting rules, single quotes are not required; the
regex is already protected by the shell from globbing. Try this instead:
[[ abc =~ a.*c ]] && echo It works
And since none of this is cygwin specific, you should report this upstream
to bug-bash AT gnu DOT org if you think it is a bug.
