--- Comment #31 from Jonathan Wakely <redi at gcc dot gnu.org> --- This seems like a property of how libstdc++ is built on riscv, or a property of the linker. I don't see how it's a libstdc++ bug though. What does 'g++ -v' show on your riscv system? (You were asked to include that information in the original report, as it says at https://gcc.gnu.org/bugs which is shown when creating a bug)
