I checked in this patch:

2000-04-04  H.J. Lu  <hjl@gnu.org>

        * readelf.c (process_symbol_table): Correctly read in symbol
        versioning information.

to fix the problem. It looks like a cut and paste bug. You can
find similar code in 2 other places, around line 3789 and line
3890. Let me know if there is any problem.

Thanks.
