Re: [Hat] hat 2.00 make failure

On a cold night last week, with the door open and a coat on, I successfully installed hat 2.00. Perhaps it was a thermal problem after all, or maybe I need to slow the processor. Best Regards, Byron At 12:27 PM 6/16/2002 +0100, you wrote:

The problem seems to be a bug in gcc 2.96: gcc: Internal Error: segmentation fault (program as)

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.
