Bug

DigitalOut interface is broken. In my case, controlling LEDs stops working. I do not see this failure when I switch to an mbed-os revision using mbed library version <= 134

Sample code:
DigitalOut RedLed(LED1);

// LED is active Low
RedLed = 0 ; // This works (LED ON)
RedLed = 1; // This works (LED OFF)
RedLed = 0; // Now broken, LED remains OFF forever

Target
MOTE_L152RC

Toolchain:
GCC_ARM

Toolchain version:
5.4-2016q3

mbed-cli version:
1.1.1

Hi @snelson-senet I changed the title to match the description.

@0xc0170 It looks like this is an STM32, and only supports mbed OS 2. Could you mention the ST people?

I created pull request #4378 to show how I fixed this issue.
Feel free to use if feasible.
