SendableChooser crashes on reinitialization of Robot

I encountered this bug when trying to obtain a list of autonomous mode names to run in the instantiation macro of a TEST_P(), but this bug would occur in any test suite that instantiates the robot more than once (say, making a new robot in each TEST() block). The following minimal example reproduces the bug with version 2020.3.2-286-g7ae8c7b.

#include <frc/TimedRobot.h>
#include <frc/smartdashboard/SendableChooser.h>
#include <frc/smartdashboard/SmartDashboard.h>

class Robot : public frc::TimedRobot {
public:
    Robot() {
        std::cout << "ctor" << std::endl;
        m_chooser.SetDefaultOption("No-op", 0);
        frc::SmartDashboard::PutData("Autonomous modes", &m_chooser);
        std::cout << "ctor end" << std::endl;
    }

    ~Robot() { std::cout << "dtor" << std::endl; }

private:
    frc::SendableChooser<int> m_chooser;
};

#ifndef RUNNING_FRC_TESTS
int main() {
    frc::RunHALInitialization();
    {
        // ctor and dtor run fine
        Robot robot;
    }
    {
        // crashes in ctor in SmartDashboard::PutData()
        Robot robot;
    }
    return frc::StartRobot<Robot>();
}
#endif

Here's the gdb backtrace:
