This is almost surely the wrong mailing list to report this problem.
Since you found that the Cygwin version of grep doesn't behave
differently than the Unix and Linux versions, it's apparently a generic
problem in grep.

Consequentially the bug report should go to the grep bug reporting
mailing list which you can find in the BUGS section of the grep man
page.  Btw., the BUGS section in the grep man page also contains some
interesting hints about situations which require lots of memory and 
exponential time/space.
