Previously, some backends like the
identity_backend
would callTRITONBACKEND_Response*
APIs even when it had anullptr
response, leading to server segfaults. While the backend can be improved to not do this, a more holistic approach for all backends is to catch this in core and gracefully return an error.NOTE: There are likely more APIs that could be checked/improved, but keeping scope small to what APIs were involved in the L0_pinned_memory failures.
