--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.
#1 0x0000000000e1d0d9 in gimple_build_assign_1 (lhs=
<ssa_name 0x7ffff6574f30 6>, subcode=NEGATE_EXPR,
op1=<ssa_name 0x7ffff6574d80 3>, op2=<ssa_name 0x7ffff6574d80 3>,
op3=<tree 0x0>) at ../../src/test/gcc/gimple.c:455
455 gcc_assert (num_ops > 2);
#3 0x00000000016294ee in rewrite_expr_tree (
stmt=<gimple_assign 0x7ffff66adaa0>, opindex=1, ops=..., changed=true,
next_changed=false) at ../../src/test/gcc/tree-ssa-reassoc.c:4963
4963 = gimple_build_assign (lhs, gimple_assign_rhs_code
(stmt),
(gdb) l
4958 {
4959 gimple *insert_point
4960 = find_insert_point (stmt, oe1->op, oe2->op);
4961 lhs = make_ssa_name (TREE_TYPE (lhs));
4962 stmt
4963 = gimple_build_assign (lhs, gimple_assign_rhs_code
(stmt),
4964 oe1->op, oe2->op);
so the rhs code is a negate while we expect sth else. I will have a look.
