forward / performv appears to be completely broken in the gcc 3.x series.  Below
is a test program.

Expected output is:

hello world
hello world

This is the output generated by gcc 2.96.

Output under gcc 3.3.2 is:

hello world
hello ˆõÿ¿ýO\x03@ð¿Øš\x10öÿ¿ð¿\x18

This may be related to bug 429 "-forward:: / -performv:: does not work with
floats/structs" but as far as I can tell forward/performv is not working with
anything now.

#include <objc/Object.h>
#include <stdio.h>

@interface Obj1 : Object
{
}
- (retval_t) forward:(SEL)asel :(arglist_t)args;
@end

@interface Obj2 : Object
{
}
- hello:(const char *)str;
@end

static Obj1 *o1;
static Obj2 *o2;

@implementation Obj1
- (retval_t) forward:(SEL)sel :(arglist_t) args
{
  [o2 performv:sel :args];

  return self;
}
@end

@implementation Obj2
- hello:(const char *)str
{
  printf("hello %s\n", str);

  return self;
}

@end

int
main(void)
{
  o1 = [[Obj1 alloc] init];
  o2 = [[Obj2 alloc] init];

  [o2 hello:"world"];
  [(id) o1 hello:"world"];

  return 0;
}
