The dreaded M-R

[Lennart Augustsson]

Hmmm, maybe a warning is the best solution in general.
Even without trying any link time resolution.

Given how hard Cale had to work to reproduce it, I think
it's a rare problem.  Maybe someone who knows the innards
of ghc could make a quick hack that turns on the M-R and
warns when there's actually sharing being lost.
