Right now, it's possbile to link against a shared library that requires a symbol from anothe shared library, and not get any missing symbol warnings during link phase. This has bit me on the butt more than once, especially with libraries with promiscuous symbol reference in other libraries (ie: libraries that know too much about each other).
You can also, I think, inadvertently create a shared library that requires nonexistent symbols and not get any warnings until run-time. Which (I think) amounts to the same problem, because the library requiring a symbol from another library should have been linked against that library to create a DT_NEEDED entry. I think.
There's a linker option to use when building libraries that eliminates this problem. In my opinion, it should be the default, but it's not, because that's not how Solaris does it or some crap like that.
