That's very interesting.  Certainly, we'd be interested in analyzing this.

Perhaps -- but it certainly also indicates a linker bug, as the linker
should tell you what's wrong before giving up.  To debug this, we'd need
all of the object files you're feeding to the linker, along with the
script.  And, to work out what's going on via a via the RealView
compiler, we'd have to look at the object files you get there as well.
