 On `Windows 7` call of `ghc-pkg` utility from `32-bit` `ghc-8.2.2`
 distribution is always ended with `Segmentation fault` error.

 With use of `Cygwin` the error can be reproduced this way: run `cmd.exe`
 and in the appeared console window execute the following commands
 {{{#!bash
 c:\Users\user.name\wrk> bash
 $ mkdir ghc-pkg-check
 $ cd ghc-pkg-check
 $ curl https://downloads.haskell.org/~ghc/8.2.2/ghc-8.2.2-i386-unknown-
 mingw32.tar.xz > ghc-8.2.2-i386-unknown-mingw32.tar.xz

 $ xz -dc ghc-8.2.2-i386-unknown-mingw32.tar.xz | tar -xf -
 $ cd ghc-8.2.2/bin/
 $ ./ghc-pkg.exe --version
 GHC package manager version 8.2.2
 Segmentation fault
 }}}

 The error arises irrespective of how and with what arguments to call `ghc-
 pkg` utility. For example, firstly I has faced the problem using `stack`
 from Windows console:
 {{{#!bat
 > stack build --arch=i386 --resolver=11.9
 }}}

 I checked another distributions of GHC for presence of this bug on
 `Windows 7`. 64-bit version of ghc-8.2.2, 32-bit and 64-bit versions of
 ghc-8.0.2 and ghc-8.4.2 are free of the problem. I **did not check** the
 problem **on another versions** of MS Windows.
