Indirectly linked list, gives gfortran "internal compiler error".
Program defines indirectly linked list with allocatable link.
gfortran reports "internal compiler error". No explanation why.
Here gfortran should either compile, or give an error message!
See attached code, No external files, no compiler flags. Output:
$ gfortran --version
GNU Fortran (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
