>Description:
It seems that code generated for handling variables of
type 'long long' is incorrect. The sample program when
run hangs. Changing the type to 'long' allows the program
to exit normally.
>How-To-Repeat:
# 1 "longlong.c"
int long_long_test(  long long x)
{
  do
  {
    x =- 1;
  } while (x);

  return 0;
}

int main()
{
  long long val = 5LL;
  long_long_test(val);

  return 0;
}
