Curious, because I have almost exactly the same environment as you:
RedHat 7.2, i686, ghc-5.02.2, hmake-3.05, gcc-2.96
and it compiles just fine for me.
However, I have seen segmentation faults in gcc which are due to
hardware errors. When I have watched this happen before, usually gcc
gives a seg fault, then if you restart the `make', it successfully
completes the task that failed before, then continues a bit further
and seg faults again. You can do that a few times, but eventually
the whole system has a hard crash.
It often means either bad RAM, or your CPU is overheating. Can you
check whether the processor cooling fans are operating correctly?
Older ball-bearing fans sometimes get sticky or clog up with dust
and no longer turn. Also, I mentioned ACPI earlier, because that is
a form of hardware/BIOS control where often the CPU fans are only
switched on in response to a thermal sensor. The Linux 2.4 series
kernels do not implement the thermal control, so it is very easy to
overheat the processor just by max-ing it out for 15-20 minutes.
