I think you hit bug http://hackage.haskell.org/trac/ghc/ticket/2747,
which is an accounting bug in the garbage collector and goes away when
you trigger more garbage collections (which -hc does, I think).
Please file a bug report anyway, so we can verify that it is indeed
not a new bug. (Since the profiler modifies the program it can turn
on or off different optimisations, so it's quite possible that there
are other reasons for this behaviour.)
I don't think compiling for profiling has anything to do with it because
when
compiling with just ghc --make -O2 Test.hs and then running with -hT
behaves as
it did with -hc and running without -hT eats up memory.
I did some further tests and it seems that this is indeed the same bug as
above.
I will try the fix and if it doesn't fix things for me I will try to put
together
a minimal case where this happens and file a new bug report.
