Comment (by YitzGale):

 According to reports on the
 [https://github.com/commercialhaskell/stack/issues/4019 stack github
 issue], this now appears to be far less common than originally thought. It
 only occurs if {{{-g}}} is set AND stripping is not enabled, and stack
 enables both of those by default. So the issue does not affect most stack
 users. It only affects those who explicitly disable stripping.
