#include <pxr/usd/usd/stage.h>

int main(int argc, const char **argv) {

    auto stage = pxr::UsdStage::CreateInMemory("simple.usda");
    std::string result;
    stage->GetRootLayer()->ExportToString(&result);
    std::cout << result << std::endl;

  return 0;
}

Result:

After enabling TF_DEBUG=*
I get this output when runing the exe manualy in a terminal:

SdfLayer::FindOrOpen('≡}x»Ç☺', '< <target: usd> >')

I would guess that '≡}x»Ç☺' is a hashed string?

When I build a release coniguration instead of debug everything works fine. A debug build gives all kind of strange errors.
