This bug was reported to me by
hvr on IRC. I fixed it in GHC yesterday, but we still need a test, and we could potentially merge this to the 7.4 and 7.6 branches:
Author: Simon Marlow <email@example.com> Date: Tue Aug 7 14:44:46 2012 +0100 Fix a bug in the handling of recent_activity The problem occurred when the idle GC was turned off with +RTS -I0. Then the scheduler would go into the state ACTIVITY_DONE_GC directly without doing a GC, and a subsequent GC would put it back to ACTIVITY_YES but without turning the timer back on. Instead if the GC finds the state is ACTIVITY_DONE_GC it should leave it there.
