DWARF unwind info is broken
As reported by bitonic

(April 2nd):
07:02 < bitonic> I'm trying to get a meaningful backtrace with DWARF, using
<https://ghc.haskell.org/trac/ghc/wiki/DWARF> as a guide. however, all I get is
`Backtrace stopped: previous frame identical to this frame (corrupt stack?)`
07:03 < bitonic> I've re-built GHC 7.10.1 using `GhcRtsHcOpts += -g` and `GhcLibHcOpts += -g`, even if
I'm not sure it's even necessary
07:04 < bitonic> are there any additional steps I should take? or any way to make sure that the binary
I'm generating is sane?
