Symbol version names are just strings, they can have a hierarchy recorded, but that hierarchy can have multiple roots: Version definition section '.gnu.version_d' contains 27 entries: Addr: 0x0000003fee4450a8 Offset: 0x0450a8 Link: 4 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: libstdc++.so.6 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: GLIBCXX_3.4 0x0038: Rev: 1 Flags: none Index: 3 Cnt: 2 Name: GLIBCXX_3.4.1 0x0054: Parent 1: GLIBCXX_3.4 ... 0x0254: Rev: 1 Flags: none Index: 18 Cnt: 2 Name: GLIBCXX_3.4.16 0x0270: Parent 1: GLIBCXX_3.4.15 0x0278: Rev: 1 Flags: none Index: 19 Cnt: 2 Name: GLIBCXX_3.4.17 0x0294: Parent 1: GLIBCXX_3.4.16 0x029c: Rev: 1 Flags: none Index: 20 Cnt: 1 Name: CXXABI_1.3 0x02b8: Rev: 1 Flags: none Index: 21 Cnt: 2 Name: CXXABI_1.3.1 0x02d4: Parent 1: CXXABI_1.3 0x02dc: Rev: 1 Flags: none Index: 22 Cnt: 2 Name: CXXABI_1.3.2 0x02f8: Parent 1: CXXABI_1.3.1 ... 0x036c: Rev: 1 Flags: none Index: 26 Cnt: 2 Name: CXXABI_1.3.6 0x0388: Parent 1: CXXABI_1.3.5 0x0390: Rev: 1 Flags: none Index: 27 Cnt: 1 Name: CXXABI_TM_1 Above from libstdc++ has GLIBCXX_3.4 -> GLIBCXX_3.4.1 -> ... GLIBCXX_3.4.15 -> GLIBCXX_3.4.16 -> GLIBCXX_3.4.17 as one chain, another one CXXABI_1.3 -> CXXABI_1.3.1 -> ... CXXABI_1.3.6 as another one and CXXABI_TM_1 as its own. It is true that often in one chain people use some prefix underscore and numbers (guess say rpmvercmp could do the job there), but they don't have to, and even if it happens to work createrepo just needs to do the parsing right. But it definitely can't pick just one of the symbol versions in case there are multiple prefixes.
