 This was observed in HEAD as of 02/07/2008.

 1. Compile a stage2 GHC with the -debug option on.
 2. Run stage2/ghc-inplace --interactive RTS -Da

 Expected result: GHCi comes up, maybe showing some extra debugging
 information
 Actual result:
 {{{
 stg_ap_0_ret... Segmentation fault
 }}}

 This has been observed on amd64/Linux and amd64/OSX 10.5.

 Interestingly, -Da is omitted from the RTS help text. Maybe
 DebugFlags.apply is known to be broken?
