What are the differences between stage2-libcpp/lex.o and
stage3-libcpp/lex.o? Ignore the fact that one will have debug info and
the other will not. Look at the readelf -S output for both files, and
see if there are any differences in sections whose names do not start
with ".debug".
Also, what linker are you using?
