System: Linux sykes 2.4.20 #1 Thu Apr 24 19:53:38 UTC 2003 ia64 unknown unknown GNU/Linux
Architecture: ia64

host: ia64-suse-linux-gnu
build: ia64-suse-linux-gnu
target: ia64-suse-linux-gnu
configured with: ../configure --host=ia64-suse-linux --enable-shared --enable-threads --with-system-zlib
>Description:
The ICE happens here:

  /* We should now be at the base of the gr/br/fr spill area.  */
  if (cfa_off != (current_frame_info.spill_cfa_off
		  + current_frame_info.spill_size))
    abort ();

Removing any line makes the ICE go away.
