--- Comment #2 from sandra at gcc dot gnu.org ---
This bug also affects pointer arrays passed as an argument corresponding to a
non-pointer assumed-shape dummy.  It's also independent of whether the called
bind(c) function is implemented in Fortran or C.

PR94331 is at least a partial duplicate of this bug.

Hi Sandra!

Hi I have a patch for this, which also seems to work for PR93 I expect to post
it in the next week, if all goes well.

Best regards,
José Rui

--- Comment #8 from sandra at gcc dot gnu.org ---
I tested the second version of the patch; it does fix the bug I observed with
an assumed-rank array argument in a Fortran subroutine with C binding called
from C having lower bound 0 instead of 1.

This is interoperability/cf-descriptor-2.f90 in the new TS29113 testsuite.

https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574115.html

I think the patch was approved modulo some small cleanup; can we get it
committed soon so I can cross it off the list of test failures I'm tracking?
