[Bug c/42224] New: 32bit pointers to 32bit pointers abort on 64bit VMS

[rupp at gnat dot com]

This is a major bug on VMS, it prevents gnatlib compilation. Please fix.

$ ./cc1 foo.c
 to_ptr32 to_int to_ptr32_ptr32
foo.c: In function 'to_ptr32_ptr32':
foo.c:28:3: internal compiler error: in int_or_pointer_precision, at
tree.c:10583


--------------> Reproducer:

$ cat foo.c
typedef char* __char_ptr32 __attribute__ (( mode (SI) ));
typedef __char_ptr32 *__char_ptr_char_ptr32 __attribute__ ((mode (SI)));

void to_ptr32 (int x)
{
  __char_ptr32 ptr = (__char_ptr32) x;
}

void to_int (__char_ptr32 ptr)
{
  int x = (int) ptr;
}

__char_ptr_char_ptr32
to_ptr32_ptr32 (char **ptr64)
{
  int argc;
  __char_ptr_char_ptr32 short_argv;

  for (argc=0; ptr64[argc]; argc++);

  short_argv = (__char_ptr_char_ptr32) malloc32
    (sizeof (__char_ptr32) * (argc + 1));

  for (argc=0; ptr64[argc]; argc++)
    short_argv[argc] = (__char_ptr32) strdup32 (ptr64[argc]);

  short_argv[argc] = (__char_ptr32) 0;
  return short_argv;
