indeed the new testcase just regressed due to commit
r14-8947-g6caec7d9ec37e6 ... :-(
Reduced testcase which fails on trunk:
program p
implicit none
integer, parameter :: n = 100, l = 10
character(l) :: a = 'a234567890', b(n) = 'bcdefghijk'
character(:), allocatable :: d, e(:)
allocate (d, source=a)
allocate (e, source=b)
print *, len (d), len (e), size (e)
call not_bindc_optional_deferred (d, e)
deallocate (d, e)
contains
subroutine not_bindc_optional_deferred (c5, c6)
character(:), allocatable, optional :: c5, c6(:)
if (.not. present (c5) .or. .not. present (c6)) stop 6
print *, len (c5), len (c6), size (c6)
if (len (c5) /= l .or. len (c6) /= l) stop 84
end
end
Expected:
10 10 100
10 10 100
After above commit:
10 10 100
10 0 100
STOP 84
This is now tracked as::
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113911
Will have to wait until the cause is found and fixed...
As it is sufficient to disable the deferred-length test,
I've done that and pushed the amended patch as
https://gcc.gnu.org/g:f4935df217ad89f884f908f39086b322e80123d0
Thanks,
Harald
