--- Comment #8 from markeggleston at gcc dot gnu.org ---
trunk (10.0 svn revision 280100)
Current state of play:
For arrays allocated at compile time bounds checking works at compile time:
program test
integer, dimension(10,10) :: x
print *, x(0,:)
end program test
$ gfortran -fbounds-check pr30802.f90
7 | print *, x(0,:)
| 1
Warning: Array reference at (1) is out of bounds (0 < 1) in dimension 1
Changing to allocated arrays and bounds checking does not work at compile time
but does at runtime:
program test
real, allocatable :: x(:)
allocate(x(10))
x = 0.0
print *, x(0)
deallocate(x)
end program test
$ gfortran -fbounds-check pr30802.f90
$ ./a.out
At line 5 of file pr30802.f90
Fortran runtime error: Index '0' of dimension 1 of array 'x' below lower bound
of 1
Error termination. Backtrace:
