Details:

I was performing some test with bootloaders on atmega1284 (testing if they can
program all the available flash) and one test included printing a floating
point number, the reason is in the file ftoa_engine which store some number in
a table and read them using lpm. It works fine when the table is stored in a
low memory address ( < 64K words) but when the table is stores in the upper 
memory region the lpm instruction cannot load the data.
