Let me tell you a story: Once upon a time we got a new server here. It was
a SMP machine, so we tried a SMP kernel compiled with egcs 1.0.3a. I never
had trouble with the compiler, so I thought it would work just fine.
So, the server was running, it was in the lab and noone used it. Then
there were (again) some complains about the 3com boomerang driver on SMP
machines (did I mention it? I'm speaking from Linux), so I wrote a little
test program which simulated a massive load of web requests. And whoops -
our new server died within minutes.
To bring this story to an short end: The server would work perfectly in UP
mode (perfectly - it didn't crash during our tests), but would crash in
SMP. A switch from egcs to gcc 2.7.2.3 cured the problems within minutes.
So, if you have problems, try gcc (or better: stick with it).
Bye,
Sascha
