Great work! If you could send me the object file , I could debug my 32-bit parser version to check out this problem with global/static data. It is hard to make any statement on whether this is a parser or avr-gcc deficiency before investigating the object file. Regards, Torleif -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19087

Hmm, That will probably be a problem. I have just piled together a lot of generated code and a library to be able to create an object with this much program memory. Would the preprocessed source (of the file with main()) be of use anyway? The library is a trick to fool avr-gcc into creating the object without failing. If I just put it all in one file and try to compile it I get errors like these: >avr-gcc -Wall -gdwarf-2 -mmcu=atmega128 -O0 largeandsimple.c -o >largeandsimple.elf c:\DOCUME~1\tsandnes\LOCALS~1\Temp/ccew.s: Assembler messages: c:\DOCUME~1\tsandnes\LOCALS~1\Temp/ccew.s:55075: Error: value of 66702 too large for field of 2 bytes at 16 c:\DOCUME~1\tsandnes\LOCALS~1\Temp/ccew.s:92562: Error: value of 66702 too large for field of 2 bytes at 52828 c:\DOCUME~1\tsandnes\LOCALS~1\Temp/ccew.s:54188: Error: value of 65542 too large for field of 2 bytes at 10009 ... Hmm, come to think of it, maybe I should report this as a bug too? Torleif -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19087

It is probably nececssary to build the entire toolchain from scratch. Something like this. 1 cd binutils 2 ./configure --target=avr-elf --with-dwarf2 3 gmake 4 gmake install 5 cd ../gcc 6 ./configure --enable-languages=c,c++ --target=avr --with-dwarf2 7 gmake 8 gmake install 9 cd ../avr-libc 10 ./configure --prefix=/usr/local 11 gmake 12 gmake install Are you familiar with the AVR port?
