Thanks! That is what I started early today, and I do indeed have an update.=
 I
can get the code to compile if I change the location of Fortran "use"
statements. Basically, it looks like this in the failing code:

module abc
...
end module abc

submodule (abc) def
contains
  module procedure xyz
    use some_overloaded_procedure ! an interface for several type-bound
procedures
    ...
  end module procedure xyz
end submodule def

This code, however, works:

module abc
...
end module abc

submodule (abc) def
  use some_overloaded_procedure ! an interface for several type-bound
procedures
contains
  module procedure xyz
    ...
  end module procedure xyz
end submodule def=
