No, what Alan (?) said was that you probably used a different version
of the linker to create the ELF executable. The later behavior is
correct and current; if you want the .debug_abbrev information, you
need to get it out of the .debug_info CU headers. There's at least
SGI's libdwarf and some code in readelf or gdb to help you do this.
