Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"f3cc34568b13abb29de7b54a5f657681e9e116ca/ghc" f3cc345/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="f3cc34568b13abb29de7b54a5f657681e9e116ca"
 Add strictness for runRW#

 runRW# isn't inlined until CorePrep, so it's good to expose its
 strictness.  Moreover, if we don't we can get obscure failures
 in coreToStg; see Note [runRW arg] in CorePrep.

 This fixes Trac #11291, and makes DfltProb1 compile with -O
 always in order to expose it more vigorously
 }}}
