Yes, I had this error too. I've solved it by adding:

    [] into driver/package.conf.inplace
and
    touch driver/stamp-pkg-conf-rts

It is not so nice that ghc-inplace dumps core if package.conf.inplace
is an empty file... I think Ian has mentioned this too.

This is where I am now. It looks like a bug in the gmp software.
It happens for me this happens when I try to rebuild the rts,
near the end of distrib/hc-build (and I guess it would happen if
you tried to just run hello.hs without rebuilding the libraries).

    This GDB was configured as "mips-sgi-irix6.5"...
    Core was generated by `ghc-6.0.1'.
    Program terminated with signal 10, Bus error.

    108             TMP_DECL (marker);
    109             TMP_MARK (marker);

I'm looking in to this now. Note that I am using an external gmp:
4.1.2, along with gcc 3.3 and gnu binutils 2.14 (though using
Irix tools doesn't seem to matter anymore).

Cheers,
