That's interesting. Try setting a low bound on the heap size.
I'm making some experiment with that, with varied result: under 1 Mega the program exited because of the limit, now I've been running with +RTS -M1M -RTS and it keeps on running with increasing memory usage (now 8124 (vir) 47808 (res) 2244 (shr)).
I've also tried a very long profiling (I run it many hours till it ended up with 9 Mega or resident memory, according to top), and these are the reports:

This last one makes me wonder: it seems to me that the report is wrong. According to heap profiling there are no memory leaks, am I right? Am I reading the report correctly?
According to heap profiling, yes, there are no heap leaks. You might still be leaking some other kind of memory...
I remember I've read something about heap profiling not showing memory leaks related with FFI, there were a discussion in the haskell-cafe mailing list. I'll keep investigating.
