GHC has pretty good heap profiling, including lag/drag/void. I hope they are
still working smoothly, although I don't think they have received much love
recently.
The lag/drag/void stuff (aka biographical profiling) was a bit broken
for a while after pointer tagging was introduced, but should be fine now.
Cheers,
