Source: diffoscope Version: 84 Severity: normal Dear Maintainer,
diffoscope 84 ftbfs in Ubuntu artful (and I think experimental but haven't checked this yet) with failures like this: ________________________________ test_item1_elf ________________________________ differences = [<Difference nm -s {} -- nm -s {} []>, <Difference alloc_system-d16b8f0e.0.o -- alloc_system-d16b8f0e.0.o []>, <Differ...r -dump {} []>, <Difference find {} -execdir llvm-dis -o - '{}' ';' -- find {} -execdir llvm-dis -o - '{}' ';' []>]>]>] @skip_unless_tools_exist('nm') @skip_if_binutils_does_not_support_x86() def test_item1_elf(differences): assert differences[1].source1 == 'alloc_system-d16b8f0e.0.o' assert differences[1].source2 == 'alloc_system-d16b8f0e.0.o' expected_diff = get_data('rlib_elf_expected_diff') > assert differences[1].details[0].unified_diff == expected_diff E IndexError: list index out of range I'm fairly sure this is down to this change in behaviour in readelf: (artful-amd64)root@aeglos:/tmp# readelf --wide --decompress --hex-dump=.data alloc_system-d16b8f0e.0.o Section '.data' has no data to dump.

(sid-amd64)root@aeglos:/# echo $? 0 which in turn is down to https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=32ec889602502348b704cfb16e65c83dc3eec095 On thinking about this, I think this is arguably a binutils bug so I've filed https://sourceware.org/bugzilla/show_bug.cgi?id=21820 too. But I thought you might want to know :) I can't see any very easy way of working around this in diffoscope but I'm new to the codebase.
