------- Comment #2 from fxcoudert at gcc dot gnu dot org 2007-08-06 21:13 ------- It's not about being allocatable, it's the I/O operation that doesn't perform the necessary check:
$ cat a.f90 real :: x(2,2) x = 0. print *, x(5,:) x(5,:) = 1. end $ gfortran -fbounds-check a.f90 && ./a.out 0.000000 5.8787666E-39 At line 4 of file a.f90 Fortran runtime error: Array reference out of bounds for array 'x', upper bound of dimension 1 exceeded -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30802
