Comment (by simonpj):

 Replying to [comment:15 rwbarton]:
 > The text library does not expect its users to follow its INLINE
 directives without also following its RULES.)

 And THAT is the GHC bug here: we are compiling a client with `-O0` but
  * we ''are'' obeying INLINE pragmas from `Text`,
  * we ''are not'' obeying RULES from `Text`.

 Right?

 Simon
