Summary: Problem compiling function that returns va_list on 64
bit system.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: x.user1...@gmail.com
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.
