I think it was poc_ref_pic_reorder() in slice.c that triggered the ICE. I
don't know if the original code shows the vectorization reduction problem.
That might only be present in the reduced testcase.

May I ask which function in h264ref also shows this issue? I instrumented GCC
and could not found a case in it. Thanks.

I am also investigating as Alan suggested in comment #3 to see how to fix the
reduction issue.

The standard way of dealing with condition reductions like this is to ignore
the contents of the "if" statement and produce a lot of code to deal with the
general case (it creates two vectors - o
