[Bug tree-optimization/16542] New: [lno] ICE with computed gotos

[reichelt at gcc dot gnu dot org]

The lno-branch crashes on the following code snippet compiled
with -O2 (C or C++ frontend):

===================================
void foo(void *p)
{
    void* a[] = { &&l0, &&l1 };

    l0: goto *p;
    l1: goto *p;
}
===================================

The error message is:

bug.c: In function `foo':
bug.c:2: internal compiler error: in tree_split_edge, at tree-cfg.c:3098
Please submit a full bug report, [etc.]

This causes a bootstrap failure in libjava.
