I have reproduced this bug on IA64 Linux and also verified that it does not
happen if the patch for PR 23478 is removed.

Fixed by one of the following patches:
2005-08-31 Richard Henderson <rth@redhat.com>
* emit-rtl.c (set_mem_attributes_minus_bitpos): Look through
component-like references for setting MEM_NOTRAP_P.
2005-08-31 Richard Henderson <rth@redhat.com>
PR rtl-opt/23601
* reload1.c (reload): Set MEM_NOTRAP_P in spill slots.
(fixup_eh_region_note): New.
(reload_as_needed): Call it.
(fixup_abnormal_edges): Allow all throwing insns to be deleted;
don't call find_many_sub_basic_blocks; call verify_flow_info.
* function.c (assign_stack_local_1): Set MEM_NOTRAP_P.
(keep_stack_depressed): Likewise.
(assign_stack_temp_for_type): Likewise; use adjust_address_nv.
2005-09-01 Jakub Jelinek <jakub@redhat.com>
PR rtl-optimization/23478
* local-alloc.c (struct qty): Add n_throwing_calls_crossed field.
(alloc_qty): Initialize it.
(update_equiv_regs): Clear REG_N_THROWING_CALLS_CROSSED.
(combine_regs): Combine also n_throwing_calls_crossed fields.
(find_free_reg): Don't attempt to caller-save pseudos crossing
calls that might throw.
* global.c (struct allocno): Add throwing_calls_crossed field.
(global_alloc): Revert 2005-08-22 change. Initialize
throwing_calls_crossed.
(find_reg): Don't attempt to caller-save pseudos crossing calls that
might throw.
