DWARF unwind info is broken

As reported by bitonic and petermw on #ghc (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?
