example project for lorawan compiling many warnings,resulting project hardfaults on nucleo L152RE

I have been trying to compile the example LoRaWAN project ( https://os.mbed.com/teams/mbed-os-examples/code/mbed-os-example-lorawan/) for my Nucleo L152RE for a couple of days noe. The compiling gives a lot of warnings on type in extras/mbed-os.lib/components/* about type conversions and stuff like "Warning: Unelaborated friend declaration is a C++11 extension; specify 'class' to befriend 'LWIP'" all of these warnings are in the mbed library so i cant see the source of the error to debug it

when i flash the program (the bin file i get inspite of all the warnings) my board hard faults before the first line of code is executed in main like so: ++ MbedOS Fault Handler ++
