There has to be one, because the problem occurs when you compile gcc

frequently with 3.x than with 2.95, in my testing, but that was not a 
test of compiling Haskell, so I have no frequency information, specifically.
    

Sounds like a CPU-overheating problem to me.  It is well known that
running an inadequately cooled processor at 100% for an extended
period will cause random crashes.  There are third-party reports
that it happens with Linux kernel builds, and I have personally seen
it with builds of nhc98 and Hat.  When I replaced the CPU fan, the
problems disappeared.

  
The other problem for the gcc people is the fact that it occurs 
randomly.  The behavior has changed; 3.4 will crash in a different place 
than 3.3.  If the program is large enough, it will happen.
    

Non-repeatable crashes certainly point the finger first at hardware
rather than software.  Could also be deteriorating memory chips -
but that is likely to bring the whole machine down eventually.

Ordinally I would agree, but in this cases it hash to be software because I got probem on 40 different solais system

As for the processor  overheating, you would expect that it's on it's last legs if it starts overheating.  It also happens on older machies; I've seen it happen on a PII machine, which isn't terribly hot.

I think that because I've seen it so many times, on machines that continue to run flawlessly, some for two years, we can eliminate hardware.  This is almost certainly heap corruption.  The KDE tool that is like purify (only better and free), valgrind, should help fix it if it is caused by any sort of memory corruption.  That would be

Remember, it is always crashing (I believe always) with an internal compiler error.  Were hardware involved, you would expect to not get the same message.  (Unless its the only error they have a name for).

If you really want to fix it, we could use a watchdog timer, and have it restart the compiler whenever it crashes.
