while (1): can't change a variable

[mappy89]

Hello everybody, i've got some problem with my Proteus

here's simplified code on C:

int flag=0;

void main()
{
  while(1)
  {
     flag++;
  }
}

It's funny, but when i download hex file to mega16 drew in proteus, variable "flag" is not changing (still 0)

I hope somebody faced with such problem and help me how to settle it.

What compiler/toolchain are you utilizing?

It maybe a simple case of compiler optimization.

Can you try with volatile int flag=0; ?
