Comment:

 The error message now says:
 {{{
   To pick the first instance above, use -fallow-incoherent-instances
   when compiling the other instance declarations
 }}}
 I hope that makes it clear why the message appears even though `-fallow-
 incoherent-instances` is set for the module that is actually being
 compiled.
