[Bug fortran/93308] bind(c) subroutine changes lower bound of array argument in caller
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93308 sandra at gcc dot gnu.org changed: What|Removed |Added CC||sandra at gcc dot gnu.org --- 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.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93308 --- 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?
