Reshape a character array inside ASSOCIATE, LEN is lost

[MR]

Consider the following code:

program test
 implicit none

 character(len=5) :: s(3), sr(3,1)

 s(1) = '12345'
 s(2) = 'ABCDE'
 s(3) = 'abcde'

 ! everything fine here
 sr = reshape(s,(/3,1/))
 write(*,*) 'len is   ',len(sr)
 write(*,*) 'shape is ',shape(sr)
 write(*,*) 'sr is    ',sr

 write(*,*) ''

 ! this should be the same as before, but len is lost
 associate( ar => reshape(s,(/3,1/)) )
 write(*,*) 'len is   ',len(ar)
 write(*,*) 'shape is ',shape(ar)
 write(*,*) 'ar is    ',ar
 end associate

end program test

The output of the WRITEs inside the ASSOCIATE construct should be the same as the previous one, however I get

$ ./test
 len is              5
 shape is            3           1
 sr is    12345ABCDEabcde
 
 len is              0
 shape is            3           1
 ar is    

i.e. the length of ar is zero, which I think is wrong.

It appears to be a bug in Intel Fortran; FWIW, the example works fine in gfortran 5.0.

Thanks for the nice example. Escalated to development as issue DPD200363229.

Steve, FortranFan, thank you.
