glib-0.12.3, which includes this fix, is available on Hackage (did you
run "cabal update"?) although there is one issue I had when installing
it.  cabal-install seems to prefer re-using an existing glib-0.12.2
rather than pulling down the new glib-0.12.3, so to make it work I had
to do:

cabal install gio --constraint="glib == 0.12.3"
cabal install gtk --constraint="glib == 0.12.3"

Sincerely,
John L.

Hm, perhaps the dependencies should be made stricter to avoid this  
kind of thing -- do you think so? I was just following the apparent  
policy of 0.12.2, which has a fairly relaxed set of dependencies.

Re: GHC 7.4+ rts_evalIO and Hackage glib-0.12.2

glib-0.12.3 is fine, it was 0.12.2 that was the problem and it wasn't
available on Hackage at the time. Now it is and I am thankful for
that.
