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?
