Comment(by dave):

 The 'right' way to fix this problem is to fix Linux (or ELF, as the case
 may be) according to Jason Merrill's suggestions in the threads "Minimal
 GCC/Linux Shared Lib + EH Bug Example," "Duplicate Data Objects in Shared
 Libraries," etc. at http://gcc.gnu.org/ml/gcc/2002-05/threads.html#02329


 As for workarounds, I'm a little unsure of how you did your linking, but
 I'm pretty sure that if base.cpp were compiled into its own shared library
 that was dynamically linked to both extension modules, you wouldn't see
 this problem.
