MAX32630FTHR throws Mutex error

[idea--list]

Description of defect

Have not been coding my MAX32630FTHR for some weeks now... Today i tried to compile my code i regularly update onto this board, but i faced unexpected issue. So i tried to compile the official blinky example with some minor additions this board needs to put 3V3 on the pins. (By default this board operates all the pins at 1V8, but even the onboard LED needs 3V3 to emit light, so max32630fthr.lib is very handy to operate this board as expected)

Target(s) affected by this defect ?

MAX32630FTHR

Toolchain(s) (name and version) displaying this defect ?

ARMC 6.15

What version of Mbed-os are you using (tag or sha) ?

OS V6.11 and V6.10

What version(s) of tools are you using. List all that apply (E.g. mbed-cli)

Mbed Studio V1.4.1

How is this defect reproduced ?

This code compiles&runs as expected up until OS V6.9 but throws mutex error on OS V6.10 and V6.11

#include "mbed.h"
#include "lib/max32630fthr/max32630fthr.h"

MAX32630FTHR max32630fthr(MAX32630FTHR::VIO_3V3);

// Blinking rate in milliseconds
#define BLINKING_RATE     500ms

int main()
{
    // Initialise the digital pin LED1 as an output
    DigitalOut led(LED1);

    while (true) {
        led = !led;
        ThisThread::sleep_for(BLINKING_RATE);
    }
}

What error is it (where is this coming from - what line is it invoking mutex error - locking in isr or is it something else)?

@0xc0170 This is all i get in terminal:

And that is what i get in Debug Console inside Mbed Studio:

Found #14465 introduced some changes to the Maxim boards. After reverting back /targets/TARGET_Maxim/TARGET_MAX32630/device/TOOLCHAIN_ARM_STD/MAX3263x.sct to the version that comes with OS V6.9 the blinky works again without mutex error. But for sure it would then affect bare-metal support which has been added with that merge.

I observed such changes several times and wonder why such things happen? I mean for sure the idea was to improve functionality and the new code may work much better in theory. But in practice even the most simple program fails to run with the newly merged code. So how new code is tested in general if not on the actual target?
