Ah, right.  Thanks for pointing me to that!

However, I do not see how such an allocator would be invoked, when Flang emits direct calls to `malloc` and `free` when compiling `ALLOCATE` and `DEALLOCATE`.  I only have seen invocations to the actual Fortran runtime allocation routines, when something like `stat` was present for the `ALLOCATE`/`DEALLOCATE` statement.
