I've updated http://developer.valvesoftware.com/wiki/Compiling_under_Linux to mention that gcc 4.x will not work.
However this behavior is surprising as I've extensively used cross-gcc version libraries before, due to the need to interface with third party products on old OSes. Generally you should be able to load a library with a new gcc as long as both libraries link to the correct runtimes dynamically. For instance http://gcc.gnu.org/onlinedocs/libstdc++/abi.html#ABI_multi_testing contains an example of essentially the exact scenario that I attempted, and it should work. My current suspicion is that gcc 4 is generating code that is invalid, possibly due to a gcc bug, or possibly due to the code containing undefined behavior, which gcc 4 interprets differently than gcc 3 did. Unfortunately due to the necessity low warning levels it's hard to say which it might be. In any case I've reverted to gcc 3.4.4 and both issues have gone away.
