[Bug rtl-optimization/32339] New: [4.3 Regression] ICE in insert_save, at caller-save.c:726

["tbm at cyrius dot com" <gcc-bugzilla@gcc.gnu.org>]

I'm getting the following ICE with current gcc 4.3.  This worked with
20070604 and is probably due to the dataflow merge.  Note that PR31025
contains a similar ICE, but the description is quite different to what
I'm seeing.  Note that my testcase shows an ICE on ia64 but works on
x86_64.

tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O2 freeciv-citydlg.c
freeciv-citydlg.c: In function 'change_callback':
freeciv-citydlg.c:15: internal compiler error: in insert_save, at
caller-save.c:726
Please submit a full bug report,

Testcase:


struct city_dialog
{
  struct city *pcity;
  char change_list_names[200][200];
  int change_list_ids[200];
};
change_callback (void)
{
  struct city_dialog *pdialog;
  int n;
  int i;
  get_city_dialog_production_full (pdialog->change_list_names[n],
    pdialog->pcity);
  pdialog->change_list_ids[n++] = i;
}
