[Bug fortran/30402] New: Bounds checking for string functions

[tkoenig at gcc dot gnu dot org]

Lots of bounds-checking errors in this program...

$ cat string_check.f90
program main
  character (len=4) :: a,b
  character (len=1) :: c
  a = 'aa  '
  b = trim(a)   ! RHS is too short
  a = repeat('b', 2)  ! RHS is too short
  c = trim(a)          ! LHS is too short, string out of bounds
  c = repeat('b', 2)   ! LHS is too short, string out of bounds
  c = a                ! LHS is too short, string out of bounds
end program main
$ gfortran -fbounds-check string_check.f90
$ ./a.out
$
