Sorry that I do not know how to reply to a specific follow-up email since I subscribed to the digest version of this mailing list.
And to Corinna: dash - usr/bin/rebaseall worked! Thank you so much for your help. Looking forward to the next update!

The problem is, the hash algorithm used by ld to compute a default DLL load address is not exactly bullet proof, not even with such a big address space we have now available for DLLs. It still requires to run rebase to be on the safe side. However, I just found a problem in the 64 distro which results in not running autorebase as part of an update. This should be fixed soon. For the time being, stop all Cygwin processes, start a naked dash and run /usr/bin/rebaseall.
