This problem was fixed in bc-1.06 which was released on Nov 16 2000.  You
can get this version on any GNU ftp mirror in /gnu/bc/bc-1.06.tar.gz.

If your distribution shipped with this old version of bc and was released
after Nov 16 2000 please file a bug report with this distribution.

>From bc-1.06/NEWS:

Changes in bc from 1.05 to 1.06:
    New multiply algoirthm and many other changes in lib/number.c
    Function size now done dynamically.
    Function syntax in non-posix mode allows newlines in more places.
    Bug fixes:
        improved computation of j(n,x).
        enables readline only if interactive.
        for statment bug fixed.
        use int instead of char for readline char counts.
