This is interesting, I also had a crash with a do while loop and I now believe that this is a bug in the compiler. Do while lets a previous loop crash. This is the proof:

Code:

---

 
int result = 0;

void test1()
{
   int i;
   for(i = 0; i < 10; i++)
   {
      result = 1;
   }      
}

void test2()
{
   
   do {
      result = 13;
   } while (result != 13);
}

void main()
{
   test1();
}

This simple program crashes all the time but works when I replace do..while by while {..}. I believe the previous for loop is somehow trashed by the do while loop. I will report this as a bug.
