A patch from Steve Kargl was sent to the fortran mailing list, (see
https://gcc.gnu.org/pipermail/fortran/2020-March/054130.html) without reference
to any PR.
It appeared to be related to this PR. I have verified the patch and also
checked it with the test case in the original report.
The result is:
5 | equivalence (i, arr(1))
| 1
Error: Array 'arr' at (1) with non-constant bounds cannot be an EQUIVALENCE
object
The above is much better than an ICE. Thanks Steve.
I will add test cases to the patch and will send it upstream for approval for
master and backports to gcc-8 and gcc-9.

Techinically, it is related to
https://stackoverflow.com/questions/60846187/fortran-equivalence-statement-with-array-length-from-subroutine-input
In the stackoverflow thread, someone mentioned this is a regression going back
to at least 6.5.
