[Bug tree-optimization/15577] New: ICE on legal

[dalej at apple dot com]

Probably an inliner bug.  Fails in mainline as of now.
g++ -O3 vv.cc
vv.cc: In function `long int intrand()':
vv.cc:8: internal compiler error: in emit_move_insn, at expr.c:2799


static long seeds[100];
long opp_nextrand(long& seed)
{
     return seed;
}
long intrand()
{
    return opp_nextrand(seeds[0]);
}


First dump after inlining (gimple) looks like
      long int<D5> <D1542>;
            <D1542> = seeds<D1530>;
which is wrong as seeds is an array.
