Hi,

This is a simple example:

long long a = 1767040273612800LL;
long long b = 2365440384LL;
long long c;

int main(void)
{
  c = a/b;
  return 0;
}

After division, "c"  has value 747009,but correct result - 747023.

Another few numbers:

  1767020750438400 / 2365439945 = 747015,
   but CrossWorks give 747008;

  1767001050316800 / 2365438870 = 747007,
   but CrossWorks give 746528 (!)

My CrossStudio(r) current version - 1.3 Build 5
(with ver. 1.2 - the same problem)

In LPC2106,S3C44B0X,ARM Simulator -  the same problem.
