Take the following invalid code:
=====================
__complex__ double _M_value;
void f(void)
{
__complex__ double __t;
_M_value *= __t;
=====================
Yes the } is missing. We get an ICE after the error. This is only with -O1 and above.

The patch which I thought caused this when I filed it is the most obvious one now:
+2005-06-09 Richard Henderson <rth@redhat.com>
+
+ PR tree-opt/20610
+ * tree.h (DECL_COMPLEX_GIMPLE_REG_P): New.
+ (struct tree_decl): Add gimple_reg_flag.
+ * integrate.c (copy_decl_for_inlining): Copy it.
+ * gimplify.c (internal_get_tmp_var): Set it.
+ (gimplify_bind_expr): Likewise.
+ (gimplify_function_tree): Likewise.
+ (gimplify_modify_expr_complex_part): New.
+ (gimplify_modify_expr): Use it.
+ * tree-gimple.c (is_gimple_reg_type): Allow complex.
+ (is_gimple_reg): Allow complex with DECL_COMPLEX_GIMPLE_REG_P set.
