This could have been caused by the recent gcc 3.4.2 upgrade.
gcc broke ABI compat once again, and you need to recompile
every C++ app. See /usr/src/UPDATING:

20040728:
        System compiler has been upgraded to GCC 3.4.2-pre. As with any major
        compiler upgrade, there are several issues to be aware of. GCC 3.4.x
        has broken C++ ABI compatibility with previous releases yet again
        and users will have to rebuild all their C++ programs with the new
        compiler. A new unit-at-a-time optimization mode, which is default
        in this compiler release, is more aggressive in removing unused
        static symbols. This is the likely cause of 'make buildworld'
        breakages with non-default CFLAGS where optimization level is set
        to -O2 or higher.

G'luck!
