f2py throws AssertionError on fortran 90 files which declare routines with C bindings (Trac #1679) #2275
Description
Original ticket http://projects.scipy.org/numpy/ticket/1679 on 2010-11-19 by trac user davidpowell, assigned to @pearu.
When running f2py on a fortran 90 file with the following contents:
interface
function my_func(x) bind(c,name='my_func')
use iso_c_binding
real(c_double), intent(in) :: x
real(c_double) :: my_func
end function
end interface
It causes an exception in f2py, ending with the following line:
File "C:\Python26\lib\site-packages\numpy\f2py\crackfortran.py", line 665, in markoutercomma
assert not f,`f,line,l,cc`
AssertionError: (1, "x@)@ bind@(@c,name='my_func'", "x@)@ bind@(@c,name='my_func'", ')')
As far as I understand this is just a bug in the parser, since f2py shouldn't care that my fortran code is internally calling C routines.

It seems this issue has had a regression: https://gist.github.com/dhermes/b27be5cc4c73d9665beff24b6c18af4f

@dhermes AFAICT from checking back to NumPy 1.6, your example has never worked. I note that it isn't quite the same as the example in this issue.

@dhermes You should open a new issue for your problem.

Done (#9693). Thanks for the reply @charris!
