--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- Created attachment 52501 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52501&action=edit Patch to fix abi-check on Solaris 11.3 This patch changes the version of the std::from_chars symbols from GLIBCXX_3.4.29 to GLIBCXX_3.4.30 for targets where they were absent in gcc-11 and are present in gcc-12 (such as Solaris 11.3). It also adds aliases for Solaris 11.4 (and later) so that they are present with both symbol versions, to support executables linked on Solaris 11.3 and expecting the symbols to have the new version.
