------- Comment #2 from jakub at gcc dot gnu dot org 2008-04-27 11:06 ------- As most of the nested calls are due to following die_sib, out of the first almost 46000 frames I've uped, there were: 20273 gt_ggc_m_10die_struct ((*x).die_sib); 8878 gt_ggc_m_19VEC_dw_attr_node_gc ((*x).die_attr); 8877 gt_ggc_m_10die_struct ((*x).base.vec[i0].dw_attr_val.v.val_die_ref.die); 7220 gt_ggc_m_10die_struct ((*x).die_child); the best fix is IMHO to mark die_sib as chain_next. Unfortunately, the DIEs are linked circularly through the die_sib field, so chain_next doesn't work properly for that. I'll post a patch which introduces chain_circular alternative to chain_next. With this patch, cc1plus with this testcase on ppc64-linux native compiles even with ulimit -s 500, which is 28 times lower stack usage than before.
