Hi - while trying to build a testcase for some [obscure] Objective-C code
I have which crashes gcc-3.0, I realized the whole thing does not seem
particularly Objective-C specific, as the C compiler crashes as well.

leonardo:~/gcc-3.0/gcc/testsuite/objc/execute$ gcc nested-3.c
/tmp/ccSXG4Kj.o: In function `test_function':
/tmp/ccSXG4Kj.o(.text+0x5a): undefined reference to `nested.0'

int test_function (int argument)
  typedef struct 
      int val[argument];
    } block;

  inline block nested ()
      unsigned i;
      block result;

      for (i = 0; i < argument; i++)
	  result.val[i] = i + 1;

      return result;

#ifndef VARIANT

  block result;

  result = nested ();
  return result.val[0];

#else /* Compile with -DVARIANT to get a different compiler crash */

  return (nested ()).val[0]; 


int main (void)
  if (test_function (5) != 1)
      abort ();

  return 0;
