Yep.
I'm using ghc-6.12 (in this case from the not-yet-really-released
ghc-6.12.2 tarball, but you get the same results for using ghc 6.12
branch (obviously) or the release candidate. Information about my ghc-6.12:

The major difference between this one and `normal' builds maybe
that I'm currently using integer-simple.
For building ghc-head, I'm using the following mk/build.mk:
HSCOLOUR_SRCS = NO
GhcLibHcOpts=-O -fgenerics -fasm
GhcStage1HcOpts=-O -fasm
GhcStage2HcOpts=-O -fasm
SplitObjs=NO
GhcLibWays=v
GhcRTSWays=
INTEGER_LIBRARY=integer-simple
SRC_CC_OPTS += -g -O0
HADDOCK_DOCS=NO
LATEX_DOCS=NO
BUILD_DOCBOOK_HTML=NO
GhcWithInterpreter = YES
GhcWithSMP = NO
Then I just run gmake and get the panic on HsExpr.lhs.
I don't know if it is of any help, but below are the lat (failing)
command line with -v, the output, and a ghc-pkg list -v (from the
ghc-6.12 I'm using for bootstrapping):
