How can I reproduce this additional error in trans-mem.c?

David, after using your patch handling NULL in
rs6000_xcoff_section_type_flags(), I can cc1/cc1plus all the aforementioned
failures in this PR correctly (with a cross to powerpc-ibm-aix5.3.0.0).

Is this similar failure you mention something else?  Is there a testcase?
