--- Comment #8 from Ben Woodard <woodard at redhat dot com> ---
One of the projects that I'm going to move to subsequently will be comparing
binaries created by different compilers. So please do not close this quite yet.
What I would suggest:

1) When abidiff opens up a binary that doesn't have debug information emit a
2) Try to reproduce the problem with libraries which have debug information.
If the problem doesn't exist the warning in item 1 should suffice.
If the problem still exists carefully look at the DWARF to understand the
problem. Then depending on what we figure out, we decide to take action.

What I'm ultimately looking for is for:
$ abidiff clang-elf-file.so gcc-elf-file.so
$ echo $?
