            Bug ID: 112263
           Summary: [C++23] std::stacktrace does not identify symbols in
                    shared library
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vincenzo.innocente at cern dot ch
  Target Milestone: ---

using 
gcc version 14.0.0 20231028 (experimental) [master r14-4988-g5d2a360f0a5] (GCC)
that contains the fix for #111936

This simple example  [1]
when run as a single executable prints all symbols in the stacktrace
when the nested functions are in a shared library their names are missing
c++ -std=c++23 testStacktrace.cpp -lstdc++exp -g -DINMAIN -DINLIB ; ./a.out
