Hi Iztok,

this is strange, I cannot repeat this bug. I've tried using gcc-3.2
with the patched ggc-page.c and the latest cvs and I can build up to
gm2.paranoid. It looks like the ggc-page.c has not been patched
(possibly) - certainly SymbolTable.mod will fail without the patch.

It might be worth checking that gcc-3.2/gcc/ggc-page.c contains:

void
ggc_collect ()
{
  return;   /* <---  this early return is for gm2 */

hope this helps,

Gaius
