RTS execution stacks are broken in GHC 8.10-9.2

Summary

The execution stack feature accessible through GHC.ExecutionStack doesn't seem to work at all under at last GHC 8.10.5 and the 9.2.0 prerelease. Trying to use either showStackTrace or getStackTrace prints an error and the stack trace ends in rts/libdw.c. This is related to #14510.

Steps to reproduce

1. Install the ghc-8.10.5-x86_64-deb10-linux-dwarf.tar.xz bindist. I also tested a self compiled version of GHC 8.10.5 and 9.2.0.20210422 with DWARF support and debug symbols. To install this bindist I used ghcup install ghc -u https://downloads.haskell.org/~ghc/8.10.5/ghc-8.10.5-x86_64-deb10-linux-dwarf.tar.xz ghc-8.10.5-dwarf.

2. Create ExecutionStacks.hs containing the following:

   module Main where
   
   import           Control.Monad                  ( forM_ )
   import           GHC.ExecutionStack
   
   main :: IO ()
   main = foo
   
   foo :: IO ()
   foo = do
       Just stack <- getStackTrace
       forM_ stack $ \(Location object fn loc) ->
           putStrLn $ maybe object sourceFile loc ++ ": " ++ fn
   

3. Compile and run this with ghc-8.10.5-dwarf -debug -g3 ExecutionStacks.hs && ./ExecutionStacks.

Expected behavior

I expect to see a stack trace containing some kind of reference to both foo and to main, and no errors.

Observed behavior

The following gets printed:
