Hi,

My old code (a bootloader) compiled with 4.0.3 + avr-libc 1.4.4 the code size is 1068 bytes, but same code compiled with 4.3.3 + avr-libc 1.6.6 the code size is 1332 bytes!

Optimization option is -Os, boot_page_xxx and boot_rww_xxx library functions are called only.

Any body here knows what happened?

Regards.
