$ [[ abc =~ a.*c ]] && echo yes
yes
$ echo ${BASH_REMATCH[@]}
abc
$ echo $BASH_VERSION
3.2.9(10)-release

Are you sure you are using the latest version of bash?  (Hint - following these 
directions, and including 'cygcheck -svr' output as an attachment would help 
here).

What part of "In bash 3.2, the [[ ]] quoting rules changed slightly" don't you 
understand?  bash 3.1.0 has different quoting rules than 3.2, whether debian or 
cygwin packaged it.  As I have not touched any of the upstream bash code in 
this area, you should not get any different behavior on this test case by 
building bash from the upstream sources, and I still haven't seen anything 
implicating a cygwin-specific bug.
