This code is a stripped version of the code I need to run to get a bigger project working. But if it somewhat works than the setup should begin by flashing a LED 4 times before continuing. Currently this works. However as you can see I have commented out the line LCDA.DrawFullScreen(fuse3(getMatch(1),getMatch(2),getMatch(3)));. uncommenting this line causes the LED's to flash continuously rather then just 4 times. The library I'm using can be found [here][1]here. Does anybody know what is going on? To me the first few lines of a program can be affected by a change somewhere this deep inside the code is a form of dark magic.

This causes the led to not turn on but moving the lines where I make pin 11 output and high one up (beyond the LCDA.Initialise(); // INIT SCREEN ) then the led will turn on. It can also be turned on by commenting out the LCDA.DrawFullScreen(fuse3(getMatch(firstnumber),getMatch(operation),getMatch(secondnumber))); line. Magic is happening...

Edit having just reuploaded the code again this time the led just remains on all the time.

edit edit Now with the following code:

#include "LCD12864RSPI.h"
#include "DFrobot_bmp.h"
#include "DFrobot_char.h"

unsigned char fuse[1024];
void setup()
{

  LCDA.initDriverPin(2,7,10); 

  LCDA.Initialise(); // INIT SCREEN  
  pinMode(11, OUTPUT); 
  digitalWrite(11,HIGH);  
  
}
unsigned char* fuse3(unsigned char* a ,unsigned char* b,unsigned char* c){
 unsigned char* fused =(unsigned char*)malloc(sizeof(char)*1024);

  int i=0;
