Instead of relying on unreliable order of execution of the library constructors and destructors, move them to individual binaries. The advantage is that the execution time and order will remain constant and will not depend on the dynamic load dependency solver. This requires more work, but that was mitigated by a simple requirement, any executable using libisc and libdns, must include <isc/lib.h> and <dns/lib.h> respectively (in this particular order). In turn, these two headers must not be included from within any library as they contain inlined functions marked with constructor/destructor attributes.
