Contruction of global static objects fails while using flash adresses over
0xFFFF, e.g. for bootloader purposes. avr mcu hangs completly before main or
even the called constructor itself.

minimal gcc call: 
avr-c++ -c -mmcu=at90can128 -I. -I. -g -O0 -Wall -Wextra -Wshadow
-Wpointer-arith -Wcast-align -Wsign-compare -Waggregate-return -Wunused
 -fno-exceptions  a_test.cpp -o a_test.o

linked with the following options
-Wl,-Map=a_test.map,--cref,--section-start=.text=0x1F000

short example code in attachment.
