------- Comment #10 from pinskia at gcc dot gnu dot org 2007-05-22 22:21 -------
#5 0x102946e0 in expand_expr_real_1 (exp=0xf7d53630, target=0x0,
tmode=VOIDmode, modifier=EXPAND_NORMAL, alt_rtl=0x0)
at /home/apinski/src/ptrplus/gcc/gcc/expr.c:8872
(gdb) p debug_generic_expr (exp)
past = then;, (void *) &past;
The problem is in expand_builtin_memmove_args, even though we do:
3475 while (TREE_CODE (result) == COMPOUND_EXPR)
We have a NOP_EXPR around the COMPOUND_EXPR, working on a fix because I was the
one who introduced the NOP_EXPR.
