Now we deliver a new libfoo.so.2. The guy who maintains our application is a real go-getter, so he relinks and redelivers binaries almost right away. When the application runs, it pulls in libfoo.so.2 and (via the libbar.so.1 dependency) pulls in libfoo.so.1 as well. Oops. Chaos ensues. You get SIGBUS and an extremely confusing to examine core dump if you're lucky, or silently corrupted user data if you're not.
At least Linux supports versioned symbols and libjpeg (and some others) were adapted to use versioned symbols so that multiple major versions of the library could be pulled in at once without harm.
Does Illumos support Linux-style versioned symbols?
