the `impossible' happened: ASSERT failed! file codeGen/ClosureInfo.lhs, line 596

I was trying to compile ghc with profiling enabled: downloaded the source for ghc-6.4.2, configured it and created the following build.mk:

avatar@avatar:~/tmp/ghc-6.4.2> cat mk/build.mk

SRC_HC_OPTS     = -H32m -O -fasm -Rghc-timing -prof -auto-all
GhcStage1HcOpts = -O0 -DDEBUG
GhcLibHcOpts    = -O -fgenerics
GhcLibWays      =
SplitObjs       = NO

Then said make in the top directory. During compilation the followinig error occured:

------------------------------------------------------------------------
==fptools== make all -wr;
 in /home/avatar/tmp/ghc-6.4.2/libraries/base
------------------------------------------------------------------------
../../ghc/compiler/ghc-inplace -H32m -O -fasm -Rghc-timing -prof -auto-all -fglasgow-exts -cpp -Iinclude -"#include" HsBase.h -funbox-strict-fields -ignore-package base -O -fgenerics  -fgenerics    -c Data/Dynamic.hs -o Data/Dynamic.o  -ohi Data/Dynamic.hi
ghc-6.4.2: panic! (the `impossible' happened, GHC version 6.4.2):
        ASSERT failed! file codeGen/ClosureInfo.lhs, line 596
