Looks like a problem with your linker script.  Somehow it is causing
the two sections to overlap.  Questions about linker scripts should be
directed to binutils@sourceware.org; see
http://sourceware.org/binutils/.

Missing __cxa_begin_catch is odd if you link with avr-g++.  It should
be provided by -lsupc++, which avr-g++ should automatically add to the
link line.
