"internal error: PAP object entered!" when running ghci compiled with profiling

With this mk/build.mk:

GhcCompilerWays=p
GhcThreaded=NO
GhcProfiled=YES
#GhcDebugged=YES
GhcRTSWays += debug_p
WAY_debug_p_HC_OPTS += -O0 -optc-O0 -optc-g
MakefileDeps = NO

I get this:

$ compiler/stage2/ghc-inplace --interactive
GHCi, version 6.9.20080315: http://www.haskell.org/ghc/  :? for help
Loading package base ... linking ... done.
ghc-6.9.20080315: internal error: PAP object entered!
    (GHC version 6.9.20080315 for x86_64_unknown_linux)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Unfortunately, there isn't a smaller example in the full testsuite.
