tried, a fairly recent, avr binutils 2.34 ( from 
https://blog.zakkemble.net/avr-gcc-builds/ ) and the error is gone . 
Also I am able to debug some firmwares using Lazarus, avr-gdb-8.3 ( 
patched by Michael Ring ) and ATBackend simulator without a problem on 
Windows 10 64bit.

What is the "official" way to build FPC avr binutils for windows ? I 
searched a little but I couldn't find anything regarding this .


PS : The above binutils have avr-as version ( GNU assembler version 2.34 
(avr) using BFD version (GNU Binutils) 2.34 ) and a avr-embedded-ld.bfd 
binary.
