--- Comment #1 from Siddhesh Poyarekar <siddhesh at gcc dot gnu.org> ---
OK I see it on x86_64 too and seems to be specific to executing from ubsan.exp
instead of dg.exp.  So the tree-objsz dump file does not seem to get generated
when -flto is present, presumably because the pass gets skipped?  The test
needs to be skipped in this case.
