gfortran 4.1 errors with

 In file t.f90:3

    integer, allocatable :: md(:), g2l(:)
                       1

  end type foo_type
                  1

      use foo_type_mod
                     1
Fatal Error: Can't open module file 'foo_type_mod.mod' for reading at (1): No
such file or directory

4.3 works.

The failure in 4.1 is due to the support of language extension TR 15581, which
was only added in 4.2.0.

It's 4.2 only and not a regression, so it will not be fixed. Closing as
WONTFIX, if someone else has a reason to suggest otherwise please speak up and
reopen it.

Sorry for the time you spent reducing it, Salvatore, and thanks for your
report.

Fair enough. While reducing the test case I also found a workaround, so it's
not a problem for me..
