Comment (by Burtannia):

 Replying to [comment:4 RyanGlScott]:
 Hi, the steps to reproduce are following the yesod quick start guide, I
 was using yesod-postgres at the time rather than yesod-sqlite:

 stack new project-name yesod-postgres && cd project-name

 stack build yesod-bin cabal-install --install-ghc

 stack build

 website-0.0.0 is because I named the project "website", if you called it
 potato then that package would be potato-0.0.0.

 ----

 Running it now is giving me a different error:

 {{{
 potato-0.0.0: build (lib + exe)
 Preprocessing library potato-0.0.0...
 [ 1 of 11] Compiling Settings         ( src\Settings.hs, .stack-
 work\dist\ca59d0
 ab\build\Settings.o )

 --  While building package potato-0.0.0 using:
       C:\sr\setup-exe-cache\x86_64-windows\Cabal-
 simple_Z6RU0evB_1.24.2.0_ghc-8.
 0.2.exe --builddir=.stack-work\dist\ca59d0ab build lib:potato exe:potato
 --ghc-o
 ptions " -ddump-hi -ddump-to-file"
     Process exited with code: ExitFailure (-1073740940)
 }}}

 I then get a dialog box telling me ghc has stopped working.

 ----

 If I use the yesod-sqlite template rather than yesod-postgres I get the
 same seg fault as before:

 {{{
