--- Comment #1 from G. Steinmetz <gs...@t-online.de> ---
A better elaborated test case :
$ cat zz1.f90
module m
interface s
module procedure a, b, a
end interface
contains
subroutine a(x)
integer :: x
end
subroutine b(x)
real :: x
end
end
$ gfortran-13-20221127 -c zz1.f90 # if necessary with -g or -O2
zz1.f90:3:30:
3 | module procedure a, b, a
| 1
Error: Entity 'a' at (1) is already present in the interface
f951: internal compiler error: Segmentation fault
