Hard to tell.  I just updated a 8.1 32 bit test machine to Cygwin
3.1.0-1 (plus lots of other packages I hadn't updated for a while) and
the update itself as well as the updated Cygwin installation worked as
desired.

I *assume* in your case there's an unfortunate combination of a bigger
Cygwin DLL in conjunction with another essential DLL overlapping the
address space.

Two things to try coming to mind:

- With the Cygwin 3.1.0 DLL installed, from Windows, double click on the
  "dash.exe" shell executable.  If that starts (it should, it only uses
  the Cygwin DLL itself), try running the `rebaseall' script.  If that
  doesn't work, try running `rebase -si > rebase.out' and send the
  output here.  Also, if there's a collision, the rebase output should
  indicate that by appending a '*' to the colliding DLLs.

- If the above fails, try to create a minimal Cygwin installation from
  the current setup-x86.exe in another directory.  If that works, maybe
  you could reinstall the packages you need and see if it still works,
  and eventually just copy over your home dir...?
