Comment (by osa1):

 bgamari, is this supposed to be fixed in GHC 8.4.1? I can reproduce this
 error:

 {{{
 $ ghc --version
 The Glorious Glasgow Haskell Compilation System, version 8.4.1

 $ cat Main.hs
 {-# OPTIONS -O -g #-}
 main = print (4, "foo")

 $ ghc Main.hs
 [1 of 1] Compiling Main             ( Main.hs, Main.o )
 Linking Main ...

 $ ./Main
 (4,"\248m@")
 }}}

 I tried with both DWARF and non-DWARF build.
