[Bug rtl-optimization/41697] New: ICE on gcc.c-torture/compile/20090917-1.c

["sje at cup dot hp dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The test case gcc.c-torture/compile/20090917-1.c looks pretty bogus
(particularly the first argument to am_vector_index_for_loop) but it shouldn't
ICE which it does on IA64 HP-UX and Linux when compiled with -O3.

The ICE happens in the selective scheduler.  I am not sure if the problem is
platform specific or not, I don't see it on any other platforms.

The error:

20090917-1.c: In function 'build_access_matrix':
20090917-1.c:55:1: internal compiler error: vector VEC(edge,base) index domain
error, in _eligible_successor_edge_p at sel-sched-ir.h:1398
Please submit a full bug report,
with preprocessed source if appropriate.
