I am trying to compile the following simple code snippet:

'''
/* test.c */
#include <stdio.h>
#include <stdarg.h>

va_list function(int i, va_list args){
	return args;
}

int main(void){
	return 0;
}
'''

I am running 64 bit Ubuntu. The code can be compiled successfully using.

gcc -Wall test.c -o test -m32

However if I compile using the standard 64 bit mode

gcc -Wall test.c -o test

I get the following error:
test.c:4: error: 'function' declared as function returning an array
test.c: In function 'function':
test.c:5: warning: return makes integer from pointer without a cast

The above code does not serve much purpose other than to demonstrate where the compiler seems to be breaking.
