------- Comment #2 from rguenth at gcc dot gnu dot org 2008-01-13 15:11 -------
Confirmed. We leak
(gdb) call debug_tree (t)
<var_decl 0xb7cb2108 e type <error_mark 0xb7ca83f0>
used unsigned SI file t.i line 3 col 10
align 32 context <function_decl 0xb7d129a0 foo>
(reg:SI 58)>
to
#2 0x08218782 in set_reg_attrs_for_decl_rtl (t=0xb7cb2108, x=0xb7caee60)
at /home/richard/src/trunk/gcc/emit-rtl.c:1009
1006 if (REG_P (x))
1007 REG_ATTRS (x)
1008 = get_reg_attrs (t, byte_lowpart_offset (GET_MODE (x),
1009 TYPE_MODE (TREE_TYPE
(t))));
because we end up expanding stuff even though errorcount is 1. Supposedly
we need to do this, but the special routine expand_one_error_var should
be more careful here.
