Note that the original bug we were fixing was on hppa, not ia64, and this test doesn't fail on hppa. On IA64 I am getting a segfault in fwprop: #0 0x496a5c0:0 in VEC_df_mw_hardreg_ptr_stack_reserve (vec_=0xc, alloc_=1, file_=0x41ac338 "/proj/opensrc/sje/reg/src/trunk/gcc/df-scan.c", line_=2881, function_=0x41aca48 "df_ref_record") #1 0x496a810:0 in VEC_df_mw_hardreg_ptr_stack_safe_push (vec_=0xc, obj_=0x40936f30, file_=0x41ac338 "/proj/opensrc/sje/reg/src/trunk/gcc/df-scan.c", line_=2881, function_=0x41aca48 "df_ref_record") #2 0x4984470:0 in df_ref_record (cl=DF_REF_REGULAR, collection_rec=0x0, reg=0x65436df8, loc=0x6543b18c, bb=0x653da048, insn_info=0x40416b80, ref_type=DF_REF_REG_USE, ref_flags=4096) #3 0x49858f0:0 in df_uses_record (collection_rec=0x0, loc=0x6543b18c, ref_type=DF_REF_REG_USE, bb=0x653da048, insn_info=0x40416b80, flags=0) #4 0x4985bc0:0 in df_uses_record (collection_rec=0x0, loc=0x65438b08, ref_type=DF_REF_REG_USE, bb=0x653da048, insn_info=0x40416b80, flags=0) #5 0x496fd40:0 in df_uses_create (loc=0x65438b08, insn=0x65438af0, ref_flags=0) #6 0x6217f60:0 in try_fwprop_subst (use=0x4044b910, loc=0x6543b1a8, new_rtx=0x652d0050, def_insn=0x65438a28, set_reg_equal=0 '\000') #7 0x621afd0:0 in forward_propagate_and_simplify (use=0x4044b910, def_insn=0x65438a28, def_set=0x65439ef0) #8 0x621b780:0 in forward_propagate_into (use=0x4044b910) #9 0x621bff0:0 in fwprop ()
