[Bug tree-optimization/27373] [4.2 Regression] ICE: add_virtual_operand with pointers to arrays

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2006-05-02 08:56 -------
ICEing in the propagator engine during copyprop:

Substituing values and folding statements

Folded statement: tt_19 = &D.1547_18->cg;
            into: tt_19 = &D.1547_12->cg;

*kaboom*

but same usual place:

#1  0x081881af in add_virtual_operand (var=0xb7d8e410, s_ann=0xb7e1a7ec, 
    flags=1, full_ref=0xb7e1a208, offset=32, size=32, for_clobber=0 '\0')
    at /space/rguenther/src/svn/trunk/gcc/tree-ssa-operands.c:1284
1284                    gcc_assert (SMT_USED_ALONE (var));

(gdb) call debug_generic_expr(stmt)
#   SMT.8D.1563_39 = V_MAY_DEF <SMT.8D.1563_14>;
D.1547_12->cgD.1522[D.1552_21] = uD.1532_16
