Comment (by Tarrasch):

 I just opened to phabricator diffs, the first being about stack
 reification in the rts. The second is more of a vision and probably more
 interesting to check out, as it's features Stack Traces in Haskell-land.

 https://phabricator.haskell.org/D661
 https://phabricator.haskell.org/D662

 Though there is still a lot of work left it seems. Right now, the biggest
 show-stopper is that D662 depends on the libdwarf library which isn't
 portable. Peter knows (much) more about this. Peter, care to give an
 update?
