Bug ID: 67900
Summary: Interface bug: Binding parameters to C causes a
compiler segmentation fault.
Product: gcc
Version: 5.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Compiling this file will cause the compiler to segmentation fault.
A simple interface declaration in which the parameter names are the same and
are binding to C causes the compiler to segfault. Usually when declaring a
generic interface that does the same operation on varied types, it is good
practice to give the parameters the same name.
The program:
program main
implicit none
interface f
function f_real(x)
real, bind(c) :: x
real :: f_real
end function f_real
function f_integer(x)
integer, bind(c) :: x
integer :: f_integer
end function f_integer
end interface f
end program main
