VERY weird 'Failed to execute MI command' problem

Hi everyone,
 
I start to question myself and this whole programming thing....
 
I'm using a STM32F3-Discovery Board and generated a code with STM32CubeMX in default mode. I changed absolutely nothing before code generation.
 
In main.c I added the following code to the default one:
 
#include "math.h"
#define PI 3.141
uint32_t sine_val[100];
 
void calcsin(void){
        for (int i=0; i<100; i++) {
        sine_val[i] = ((sin(i*2*PI/100) + 1)*(4096/2));
       }
}
 
That's all. So nothing special at all. The thing is, everything is fine but whenever I try to call calcsin() in the int main function I get the following error:
 
Error in final launch sequence:
 
Failed to execute MI command:
load E:\\STM32\\Workspace\\090924\\Default\\Debug\\Default.elf 
 
Error message from debugger back end:
Error finishing flash operation
 
Also the STM32CubeIDE opens another error message (sporadically?!) which says "No source available for "__muldf3() at 0x8000754"
 
Can somebody please help?
