I assume you are using the eCos-centric binary packages? It seems to just
be a bug in some versions of GNU ld.

If you are compiling your code with -ffunction-sections and/or
-fdata-sections then removing those two options might help (at the expense
of bloating your image).

If that doesn't work the lamer solution is to change around link order. We
never investigated it further due to time constraints (imagine how bad
things would be for us if we tracked down every Tornado problem. hehe).

Our solution has been to not compile with multi-section objects. The
benefit of multi-section objects is that if you have a source file with 10
routines by you only call one of them then only one gets linked in. So
we're still waiting for UNIX linkers (a personal rant of mine) to catch up
to the 80's.

Hope this helps,
