what error do you see? the one that recommends rebuilding with
-ffunction-sections?

in your application, do you first build some .o's, link them together
into a bigger .o, and then use those to create your final application
image? (otherwise i don't think this problem should occur; if it does
there's a bug somewhere that we should fix).

we have (or, rather, Dave has) been fixing this in various places. This
problem happens much less frequently now than it used to. Fixes may be
required either in gcc or in the linker to detect when a branch target
is too far away and needs to be converted to a long branch.
