The main problem is in the predicate passed to the `std::stable_sort()`. This predicate always returns false if **both** section's names do not start with `.init_array` or `.fini_array` prefixes. In short, it does not define a strict weak orderng. Suppose we have the following sections: .A .init_array.1 .init_array.2 The predicate states that: not .init_array.1 < .A not .A < .init_array.2 but .init_array.1 < .init_array.2 !!! The second problem is that `.init_array` section without number should go last in the list. Not it has the lowest priority '0' and goes first. The patch fixes both of the problems. llvm-svn: 209875
