Version of flang: 22.0.0git (https://github.com/llvm/llvm-project.git 2f7e218017db69454ea84e1849fcb9a11b1f7fef)
```
Flang causes an internal error while compiling the sample program with multiple pointers to the same procedure shown below.
test.f90
``` fortran
Module m1
external::sub
type ty
procedure(),pointer,nopass :: ptr5=>sub
end type
procedure(),pointer:: ptr6=>sub
end module
use m1
integer::jj =4
call ptr6(10)
print*,"Pass"
end
subroutine sub(a)
integer::a
print*,"sub"
end subroutine
```
No compiler options are needed.
