two possible reasons: the library that loads libCore is not opening it with RTLD_GLOBAL, or you have two versions of the library loaded in two different linker namespaces.

Setting LD_DEBUG to 'symbols' should give a clue. It will show which libs are considered for resolving the symbol that appears to be missing.
