Разобраться, почему так происходит.

$ rpm -ql amarok |xargs fgrep -l __cxa_pure_virtual |xargs -Ix -n1 /usr/lib/rpm/ldd --bindings x '' |& grep __cxa_pure_virtual |sort -u -k4,4 -k7,7
     28807:     binding file /usr/lib/kde3/bin/amarok [0] to /usr/lib64/libstdc++.so.6 [0]: normal symbol `__cxa_pure_virtual' [CXXABI_1.3]
     28814:     binding file /usr/lib/kde3/bin/amarokapp [0] to /usr/lib64/libmysqlclient.so.16 [0]: normal symbol `__cxa_pure_virtual' [libmysqlclient _16]
...
$ nm -D /usr/lib64/libstdc++.so.6 |fgrep __cxa_pure_virtual
00000000000ba8c0 T __cxa_pure_virtual
$ nm -D /usr/lib64/libmysqlclient.so.16 |fgrep __cxa_pure_virtual
00000000000b9ad0 W __cxa_pure_virtual
$ objdump -p /usr/lib/kde3/bin/amarok |grep -w NEEDED |egrep 'stdc|mysql'
  NEEDED               libstdc++.so.6
$ objdump -p /usr/lib/kde3/bin/amarokapp |grep -w NEEDED |egrep 'stdc|mysql'
  NEEDED               libmysqlclient.so.16
  NEEDED               libstdc++.so.6
$

Т.е. в libmysqlclient.so.16 имеется weak symbol, а в libstdc++.so.6 -
нормальный.  Но libmysqlclient.so.16 в списке требуемых библиотек идёт
раньше, что по идее не дложно помешать предпочесть нормальный символ.

Может, Зинка взяла^W^Wglibc глючит?
