Subject: Compilation fails for Altix (IA64)

During compile of the 08-26-2004 stable snapshot, I get a warning:

  gcc -g -O2   -I. -I.  -c eval.c
  eval.c: In function `massign':
  eval.c:4912: warning: cast from pointer to integer of different size

For convenience,

  4907            assign(self, list->nd_head, RARRAY(val)->ptr[i], pcall);
  4908            list = list->nd_next;
  4909        }
  4910        if (pcall && list) goto arg_error;
  4911        if (node->nd_args) {
  4912            if ((int)(node->nd_args) == -1) {
  4913                /* no check for mere `*' */
  4914            }
  4915            else if (!list && i<len) {
  4916                assign(self, node->nd_args, rb_ary_new4(len-i, RARRAY(val)->ptr+i), pcall);

The make eventually fails with,

  gcc -g -O2    -rdynamic  main.o dmyext.o libruby-static.a -ldl -lcrypt -lm   -o miniruby
  ./lib/ftools.rb:204: [BUG] Segmentation fault
  ruby 1.8.2 (2004-08-26) [ia64-linux]

And

  gdb miniruby
  r mkconfig.rb rbconfig.rb

provides,

  Program received signal SIGSEGV, Segmentation fault.
