[Bug fortran/61450] ICE in gfc_global_used()

[dominiq at lps dot ens.fr]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61450

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
With the updated patch below the ICE is now replaced with

pr61450.f90:6:15:

   integer i1
            2   
   bind(c,name="foo") :: i1

 end module



 subroutine truc() bind(c,name="foo")
               1

Error: Global binding name 'foo' at (1) is already being used at (2)

Any reason why the original patch has been delayed for more than a year?

If it helps, I can take care of the packaging.

Dominique
