C gcc-3.0 compiler crash

[Nicola Pero <n dot pero at mi dot flashnet dot it>]

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'
collect2: ld returned 1 exit status

leonardo:~/gcc-3.0/gcc/testsuite/objc/execute$ gcc -DVARIANT nested-3.c
nested-3.c: In function `test_function':
nested-3.c:33: Internal compiler error in assign_stack_temp_for_type, at
function.c:663

int test_function (int argument)
{
  typedef struct 
    {
      int val[argument];

  inline block nested ()
    {

      block result;

      for (i = 0; i < argument; i++)

      return result;
    }
