i dont know the reason but the problem could be shrink down to

func2()
{
}

func1()
{
  printf( "%d\n", func2() );
}

int main()
{
  printf( "%d\n", func2() );
  printf("%d\n",func1() ) ;
}

u will notice that the return value from func2(which does not specify 
any explicit return value)
differs when called from main() and from func1()..

this is not a problem about the ternary operator..
this is an issue about the use of implicit/explicit return values...
why are u not  making use of explicit return? and explicit use of int as 
the return type in the
function declarations??
