I've now done a 3-stage bootstrap using exactly the same versions of GHC
4.04, gcc 2.95.2 and Solaris 7. Everything worked without a hitch.

You could try building your RTS with debugging options (look in
fptools/mk/config.mk for the details). This is the RTS on the stage 1
compiler. Then relink the stage 2 compiler, and run gdb again. You should
get more informative debugging info.
We'll hold off on 4.06 until we've got a better handle on this one.
Cheers,
