Comment (by Tarrasch):

 Thanks for the rescoping @bgmari! Once we've merged something like
 Phab:D963. Then we can create new tickets for (i) getting it to use DWARF
 and a ticket for (ii) giving stack traces to Haskell land exception
 handlers.

 Phab:D963 does actually not even use the DWARF stuff. See the abandoned
 patch Phab:D662 for an implementation using that. Phab:D662 got abandoned
 since it did too much at once.
