I think that's likely.  The way to confirm this is to bootstrap
just the C language with HP's compiler and install.  Then, do another
bootstrap using the newly built 4.2.1.  A segmentation fault this
early in the build process usually indicates some module has been
miscompiled by the bootstrap compiler.

I don't know how you built 3.3.6.  There were problems with some
gcc binaries distributed by HP.  3.3.6 should work as a bootstrap
compiler.  However, the 3.3 branch is closed and 3.3 problems won't
be fixed.

Run cc1 under gdb.  Use the set args command to set the cc1's arguments
to the above list.  Then, run cc1.  This will duplicate the fault under gdb.
