Description Marek Polacek 2023-08-16 14:45:45 UTC 
gcc-toolset-12-gcc-12.2.1-7.4.el8 on i686 has a problem:

+ grep 'HIDDEN.*UND'
+ grep -v __dso_handle
   237: 00000000     0 NOTYPE  GLOBAL HIDDEN   UND _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE9_M_mutateEjjPKcj
   238: 00000000     0 NOTYPE  GLOBAL HIDDEN   UND _ZNSt7__cxx1112basic_stringIwSt11char_traitsIwESaIwEE9_M_mutateEjjPKwj

causing

/opt/rh/gcc-toolset-12/root/usr/libexec/gcc/i686-redhat-linux/12/ld: lib/libwebkit2gtk-4.0.so.37.63.5: hidden symbol `_ZNSt7__cxx1112basic_stringIwSt11char_traitsIwESaIwEE9_M_mutateEjjPKwj' isn't defined
/opt/rh/gcc-toolset-12/root/usr/libexec/gcc/i686-redhat-linux/12/ld: final link failed: bad value

gcc12-libstdc++-compat.patch needs two .hidden directives for those two symbols.
