I'm using gcc 3.4.6.
But I agree with Russell, if it was such a problem it would hit on the
first iteration of my application and not after 1 day of executing the
same piece of code...

One thing you might think about is running memtest86 on the machine
for the same kind of time interval, just in case it's something trivial
like bad ram.

OK. That's another thing to do.

Meanwhile I've switched to another SBC and I'm now running my application on the new unit. Lets wait and see...
