Does below look like a sane approach?
1) get all deps via
$ apt-cache rdepends libice6 libice-dev
2) unpack each of the above .debs and scan for ELFs
3) for each ELF see if one of now hidden symbols is UND
That sounds good to me.
I've cooked a simple script (attached, reviews welcome) and applied it
to Ubuntu 14. It showed that there are additional uses for
_IceTransNoListen (mentioned by Alan in separate email) but nothing else.
Note that this does not handle transitive dependencies e.g. if some
weird library links static version of libICE and the re-exports it's
symbols as part of new lib's public interface.
It'd be possible to scan for this too I suspect. Look for packages
that BuildRequire libice6-static, scan the resulting binaries for
exports. I suspect there are zero such packages.
I have postponed this activity for now (especially given that this
behavior would be a serious packaging abuse).
Here's an updated patch with added _IceTransNoListen. Does this look
better now?
Ping.
