! { dg-do compile }

! PR fortran/33917

!

! Depending, in which order the symbol tree

! was walked in resolve, gfortran resolved

! p6 before p4; thus there was no explicit

! interface available for p4 and an error

! was printed. (This is a variant of proc_decl_2.f90)

!

! Additionally, the following contrain was not honoured:

! "C1212 (R1215) [...] If name is declared by a procedure-declaration-stmt

! it shall be previously declared." ("name" = interface-name)
