Nonsensical error

[Salvatore Filippone]

Hello,
With the current trunk I am getting this error message, which I find
rather nonsensical (yes, if I put a "call" in front of it, it better
not be a function, thank you very much :) )
=======================================
psb_s_renum_impl.F90:298.22:

    call a%mv_to(acsc)
                      1
Error: 'psb_s_mv_to' at (1) is not a function
psb_s_renum_impl.F90:314.34:

    call acsc%mv_to_coo(acoo,info)
                                  1
Error: 'psb_s_mv_csc_to_coo' at (1) is not a function
psb_s_renum_impl.F90:319.24:

    call acoo%fix(info)
                        1
Error: 'psb_s_fix_coo' at (1) is not a function
psb_s_renum_impl.F90:323.22:

    call a%mv_from(aa)
                      1
Error: 'psb_s_mv_from' at (1) is not a function
===========================================
The resolution from generic to specific name is correct.
The code compiles cleanly with 4.8.1.
Is there any obvious suspect?
Will cut a test case and open a PR asap.
