Just thought I'd mention that I get the same result when setting the limit using C hooks (RtsFlags?.GcFlags?.maxHeapSize) --k

Further notes on this one: I can't reproduce the problem with the submitter's test case. It appears to be something system-dependent; Ketil can still reproduce it. Looking at a log of one of the offending runs, it seems the heap size levels off at the -M limit as expected, but the top output shows the process still growing.

I'm following up with Ketil to find out who/what is allocating the extra memory.

I've finally gotten around to build ghc 6.6 with the recent patch for this problem, and it appears the problem has been fixed. My program (rbr) now stick within the specified heap, until it OOMs (as expected). Thanks!
