------- Comment #6 from jakub at gcc dot gnu dot org 2010-01-28 08:03 ------- If libstdc++ relies on ODR, then RTLD_DEEPBIND can break its assumptions, as then the same symbol which is defined in multiple shared libraries can resolve to different addresses (RTLD_DEEPBIND means first the dlopened library and its dependencies, and only after it the global search scope, will be searched).
STB_GNU_UNIQUE object ought to cure it, though it is only in 4.5 (and 4.4-RH) gcc and sufficiently new binutils and glibc are needed for it too. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42679
