--- Comment #4 from Simon Marchi <simark at simark dot ca> ---
Here's a simpler reproducer:

---
#include <memory>

int main() {
  std::unique_ptr<int> p(new int);
  return 0;
}
---

$ g++ --version
g++ (GCC) 11.1.0
$ g++ -g3 -O0 test.cpp
$ readelf --debug-dump a.out
...
 <3><968>: Abbrev Number: 79 (DW_TAG_member)

    <96e>   DW_AT_decl_line   : (data1) 125
