program toto
implicit none
real :: a(10)
integer :: i
a(:) = 1.
do i=1,100
if( i <= 10 .and. a(i) > 0. ) write(*,*) i,a(i)
enddo
end
Compiling this program with -fbounds-check will give an out-of-bound error
because the bound checking happens before the evaluation of the expression.
As short-circuit (i.e. not evaluating the second part of the expression when
its result is determined by the first part) is used by gfortran, it would be
nice to use it also for bound checking (at least as an option).
