 [ 4 of 11] Compiling Reflex.Dom.Internal ( src\Reflex\Dom\Internal.hs,
 dist\build\Reflex\Dom\Internal.o )
 ghc.exe: internal error: checkProddableBlock: invalid fixup in runtime

 }}}

 This happens with unmodified reflex-dom.cabal (which specifies -funbox-
 strict-fields and -O2) and also with all ghc-options: flags removed and -O
 or -O0. When compiling with the bundled mingw it also pops up a GUI error
 window:

 {{{
 ghc.exe - Entry Point Not Found

 The procedure entry point pthread_cond_timedwait_relative_np could not be
 located in the dynamic link library libwinpthread-1.dll.
 }}}

 I also tried using a fully-updated mingw64 from MSYS2, which has solved
 -pthread issues for me in the past, but that simply crashes with no
 additional message.

 Verbose cabal output attached.
