With
integer(8), parameter :: n=2_8**31 - 1_8
I get (compilation time ~4 minutes)

'xxx', 'xxx'
With
integer(8), parameter :: n=2_8**32
I get (compilation time ~4 minutes)

'', ''
For n=2_8**31 and n=2_8**32-1, the compilation did not finished in more than
hour and I gave up).
Is there a way to check that the type of expr->value.character.length in
gfc_conv_substring_expr (fortran/trans-expr.c) is gfc_charlen_t?
