Created attachment 50346
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=3D50346&action=3Dedit
tar including all the source files.

The internal compiler error happens with GNU Fortran (Homebrew GCC 10.2.0_4)
10.2.0 .  The homebrew maintainer confirms this error and further reports t=
hat
the same error occurs on Ubuntu, too (I don't know the version of gfortran).
See https://github.com/Homebrew/homebrew-core/issues/72865 .  The maintainer
recommends submitting this report here.

Expand the attached tar file, cd to that directory, and on the command line:
````
$ gfortran -c numeric_kinds.f90
$ gfortran -c indices.f90
$ gfortran fix-track-partials-00.f90 indices.o
f951: internal compiler error: in record_reference, at cgraphbuild.c:64
libbacktrace could not find executable to open
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://github.com/Homebrew/homebrew-core/issues> for instructions.
