That is interesting, it only fails on the two 32bit systems.
The failure is about the specific error message returned.

FAIL: run-dwflsyms.sh

So there is some subtle difference in the behavior of the
'segment_report_module: Inline consider_notes() into only caller'
patch.

I haven't spotted it yet, but I suspect some 'return' from the original
function got mistranslated as a continue, break or goto out in the
inlined variant.

The specific testcase that fails is:
testrun_compare ${abs_builddir}/dwflsyms -e testfile66 --core=testfile66.core

Which is a big endian ppc64 executable and core file.

Cheers,

Mark
