An assertion has been added to symfind.cc to ensure that the ancestors vector is not empty before accessing its last element. This change addresses a false positive from the -Warray-bounds compiler warning, which incorrectly assumed the vector was empty, leading to a warning when back() was called. This does not change functionality, only avoids a spurious warning.
