When process "new" ,STM32F103C8 "Bluepill" freeze.

[human890209]

Hi,
I tried using STM32F103C8 "Bluepill" today. Cause it is supported by Arduino IDE.
Everything is here. https://github.com/rogerclarkmelbourne/Arduino_STM32
I tested the Blink example both with Arduino IDE and Sloeber, they both worked!
Then I continue to do more tests with Sloeber, cause it's better for me:>
Then I got this bug with "new". Here I paste the simple bug reproduce sketch code.

class MYCLASS
{
public:
	MYCLASS(){content = 99;};
	~MYCLASS(){};
	byte content;
};

MYCLASS mc;

MYCLASS* mcp;

void setup()
{
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
	Serial.println("loop");
	digitalWrite(LED_BUILTIN, HIGH);
	delay(500);
	digitalWrite(LED_BUILTIN, LOW);
	delay(500);
	Serial.println(mc.content);
	mcp = new MYCLASS();
	Serial.println((*mcp).content + 1);
	delete(mcp);
}

SerialMonitor(Sloeber):

Connect to serial portCOM3 at115200
99

I tried the same code in Arduino IDE. Everything works fine! (Took me much time to find out it's not a pure hardware bug...Asked around on the STM32 Arduino Github Issues and Forum, cause Arduino IDE works fine, I came here to find a way out.)

This is my project setting of Sloeber

Simply use the same default setting to Arduino IDE.

I'm sure "new" is the problem. Cause mcp = &mc; works fine with Sloeber.

Hope you could help me out with the "new"+"STM32 Bluepill"+"Sloeber" bug.
It will be awesome if STM32 Bluepills can be used with Sloeber. When Flash and SRAM get larger Sloeber is in need.

I found a warning in the compiling log. Maybe this could do some help.

Great you fixed this yourself.

The solution suggested above was a work around. The real problem has actually been fixed by #1005
