Subject: a.out behavior

The following code should obviously segfault:
#include <stdio.h>
#include <syslog.h>

char buffer[4028];

void main() {
	int i;
	for (i=0; i<=4028; i++)
		buffer[i]='A';
	syslog(LOG_ERR, buffer);
}

Now here's the problem:
When compiling with "gcc file.c", the program segfaults.
When compiling with "gcc -o file file.c", the program doesn't segfault.
Both files are nevertheless identical, apart from the name of the
temporary object file name which could be made the same (search for cc00,
perhaps).

I'm using freebsd 2.2.5, gcc 2.7.2.1. Someone please let me know what's so
special about a.out.

Thanks in advance,
Marc
