void exit(int return_code) code enters in to while loop and never returns

Hello,

I Am facing this issue from yesterday. I have no idea what would be mistake. I am using Stm32l073 controller to flash my code and unfortunately I am unable to transmit data from pc to my device but able to receive. I did then debug the code and found that it enters in to void exit function in retarget.cpp file and stuck at while loop. I have no idea what would cause this kind of problem and how to solve this. Could anyone had this issue. Kindly provide me how to solve this issue .Thanks

namespace std {
extern "C" void exit(int return_code) {
#endif

#if DEVICE_STDIO_MESSAGES
#if MBED_CONF_PLATFORM_STDIO_FLUSH_AT_EXIT
    fflush(stdout);
    fflush(stderr);
#endif
#endif

#if DEVICE_SEMIHOST
    if (mbed_interface_connected()) {
        semihost_exit();
    }
#endif
    if (return_code) {
        mbed_die();
    }

    while (1);
}
