Failing to get line numbers with Boost stacktrace + backtrace

I'm trying to reproduce the first and simplest example in the Boost Stacktrace documentation.

#define BOOST_STACKTRACE_USE_BACKTRACE

#include <boost/stacktrace.hpp>
#include <iostream>

void bar(int n) {
    if (n <= 0) {
        // ... somewhere inside the `bar(int)` function that is called recursively:
        std::cout << boost::stacktrace::stacktrace();
        return;
    }
    bar(n-1);
}

int main() {
    bar(4);
}

And am only having partial success: I'm getting the function name, but not the line:

 0# bar(int) in ./plain_vanilla
 1# bar(int) in ./plain_vanilla
 2# bar(int) in ./plain_vanilla
 3# bar(int) in ./plain_vanilla
 4# bar(int) in ./plain_vanilla
 5# main in ./plain_vanilla
 6# __libc_start_main at ../csu/libc-start.c:342
 7# _start in ./plain_vanilla

(my source file is named plain_vanilla.cpp and my executable is plain_vanilla.) I'm using Boost 1.73.0, which I built, on a Devuan 3.0 GNU/Linux. libbacktrace is installed (it's part of glibc) and I'm linking against it.

Is this more likely something I've done wrong, or is it an actual bug in the library?

To get more information in the stack track uses a debug build. For GCC compile a project with the flag -g or -fno-omit-frame-pointer.
