First we have to trip the problem in a simple native way.
Then we report it to (probably) binutils.
If it does turn out to be indirection through a table
via a function in another module, the workaround
is most likely to (unfortunately) change the user's
configuration table to call the wrapper directly.
We need a small test case native that breaks. Then we
track it down.
