Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed| |2023-11-17 Status|UNCONFIRMED |WAITING Component|c++ |libstdc++ Ever confirmed|0 |1 --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- std::regex doesn't work in any release older than gcc-4.9.0 so I doubt it's working properly with gcc-4.8.5 If it is working properly, then you're not actually using std::regex, so you should just be able to remove it. In any case, we can't do anything without the information we request for all bug reports: https://gcc.gnu.org/bugs/
