Comment (by basvandijk):

 [[https://mail.haskell.org/pipermail/ghc-devs/2019-January/016748.html|As
 explained on GHC-devs]] I ran into this in our `haskell-opencv` library. I
 can confirm that adding the following to the cabal file of my minimal
 isolated test-case fixes the problem:

 {{{
 if os(darwin)
   ld-options: -Wl,-keep_dwarf_unwind
 }}}

 Shouldn't GHC pass these options by default when linking on OS X?
