Hello,
The attached file is an example of how tangle wraps the Fortran module in
program main
end program main
which prevents the code from compiling.
There are more instructions on how to reproduce the bug in the attached
bug.org file.

Run with
/usr/bin/emacs -Q -l init.el bug.org
One should be able to click on the following link
- elisp:org-babel-tangle
to tangle (export) the code blocks in this org file.
Then one should be able to execute the code block
- [[code_block_to_execute]]
by using C-c C-c in code block.
However, it does not work because the tangle stage wraps the fortran
module in
program main
end program main
which prevents the code from compiling.

I opened the latest Org git repo, ran make repro, opened the file,
clicked on "tangle" link, moved to the linked source code, and executed
it. It worked.
So, I am unable to reproduce the problem on my system.

Hello Ihor,
Thanks for investigating. Can you please post your tangled file named
circle.f90.
Mine looks like this
program main
MODULE Circle
implicit None
public :: area
contains
function area(r)
implicit none
real, intent(in) :: r
real :: area
area = 3.14159 * r**2
return
end function area
END MODULE Circle
end program main
which is broken because org/babel has added the first and last lines.
Thanks,
Paul

Never mind my previous message. I forgot the provided init.el file,
which makes all the difference.
Confirmed.
By default, ob-fortran (and at least ob-C) wrap the src block body to
become a standalone function unless you put :main no header argument.
The default behaviour is mostly useful during execution, but not when
tangling.
I will need to think about the best way to approach this. A tentative
fix would be handling :main header argument only during block evaluation.
Meanwhile, you can set :main no as default header argument for fortran.
