That is contrary to the specification of the SVR4 ABI, page 4-27: "Similarly, if a common symbol exists (i.e., a symbol whose st_shndx field holds SHN_COMMON), the appearance of a weak symbol with the same name will not cause an error. The link editor honors the common definition and ignores the weak ones." The paragraph you quote starts with "When the link editor combines several relocatable object files...." So a shared library should be treated like a random .o file, instead of like an archive library? That seems counterintuitive. Is a shared library really considered a "relocatable object file"? The ABI description doesn't seem all that clear to me, actually. At the start of chapter 4, it's described as a third type of object file, distinct from relocatable files and executable files.
