Bug ID: 105678 Summary: Undefined reference to stacktrace standard library Product: gcc Version: 12.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: fcolecumberri at hotmail dot com Target Milestone: --- I'm trying to test the stacktrace C++23 feature by creating the next program: ```c++ #include <stacktrace> int main(){ std::stacktrace::current(); return 0; } ``` using the next g++: ``` Using built-in specs.
