The attached testcase ICEs on ppc*-linux with -O2 -m32 and -O2 -m64:
internal compiler error: in compute_antic, at tree-ssa-pre.c:2020
2019 /* Theoretically possible, but *highly* unlikely. */
2020 gcc_assert (num_iterations < 50);
num_iterations is 50.
The code is distilled from staden-io_lib, see http://bugzilla.redhat.com/450889
