------- Comment #2 from rguenth at gcc dot gnu dot org  2010-08-07 10:44 -------
Confirmed.

(gdb) call debug_gimple_stmt ($1)
.MEM_15 = PHI <.MEM_19
Program received signal SIGSEGV, Segmentation fault.
0x08384621 in gimple_phi_arg_edge (gs=0xb77611b0, i=0)
    at /home/richard/src/trunk/gcc/tree-flow-inline.h:479
479       return EDGE_PRED (gimple_bb (gs), i);

Immediate uses are hosed before DSE.  And partial inlining is the cause.
