Details:

The strtod() -function alters EIND at the end and calls 
" __prologue_saves " in ATmega2560.
After that, any function call that uses EICALL fails probably because EIND
was set to the wrong value in strtod().

It may depend on code size whether EICALL succeed or not. This seems to
happen when codesize pass around 50% of available flash memory in ATmega2560
because everything is working below this limit.
