 Recently, GHC stopped working for me on my Windows 10 machine.

 I strongly reckon this has to do with my recent switch to the Windows
 Insider Fast-Ring builds: I'm currently on version 1703, build 15058.

 Here's what I got in a mingw shell (ghc 8.0.2 from the core HP, same
 output with PowerShell):

 {{{#!hs
 $ cat << EOF > hw.hs
 > main = putStrLn "hi"
 > EOF
 $ ghc hw.hs
 [1 of 1] Compiling Main             ( hw.hs, hw.o )
 `gcc.exe' failed in phase `Assembler'. (Exit code: -1073741502)
 }}}

 This seems to be independent of the GHC version, as I tried `stack setup`
 with different stack LTSs, which hit the same error when compiling some
 sanity checks.

 Currently I'm about to reverting back to Slow-Ring, but when the actual
 switch is to happen is only known to Bill Gates himself it seems. I
 believe it will then work again, but this is something to look out for
 when/if the Fast-Ring changes eventually make it into Windows stable.
