No, this change wasn't sufficient.  There's something in the symbol table emitted on the tools on the builder that causes lldb to miscalculate the extent of the "spacing" such that its range encompasses the branch island symbols.  That's why when we stop at the branch island, the stop address is attributed to the padding symbol that's at the beginning of the section and not the islands that the linker inserted at the end of this space.
