> 2011-10-20 Jan Kratochvil <[email protected]> > > * dwarf2out.c (struct dw_loc_list_struct): Add GTY for expr; This patch is a no-op, as already pointed out. If this comes up again, I'd set a conditional breakpoint on ggc_set_mark if (arg == struct dw_loc_list_struct with the field that gets collected) and try to find out why the field does not get marked. -- Laurynas
