There is a problem with your code; it's not an EGCS bug, and has
nothing to do with the STL.

You've broken the "one definition rule" by defining i1 twice. If you
intended each of the two modules to have its own separate version of
i1, you should either declare them "static" or put them in an
anonymous namespace. If you intended them both to share a single
global i1, you should declare it "extern" in a header file and define
it in only one of the source modules.
