Memory corruption

[Ulf Carlsson <ulfc@thepuffingroup.com>]

Hi,

The compiler may stop working sometimes on certain files, giving bogus error
messages which I don't understand (the compiler is probably not the only
application affected).  Running this program I just wrote forces the corrupted
caches to be flushed or something and ``fixes'' the problems:

int main(void)
{
	unsigned long tot = 0;
	unsigned long i = 1 << 20;
	void *p;
	int failures = 0;

	while (i) {
		p = malloc(i);
		if (!p) {
			if (failures++ < 10)
				continue;
			i = i >> 1;
			failures = 0;
			continue;
		}
		memset(p, 0, i);
		tot += i;
	}
	printf("Total memory set: %u kb\n", tot >> 10);
}

Maybe I should put this in my crontab along with sync :-)

Does anyone else notice these problems?
