JakeChampion opened a new pull request, #12905: URL: https://github.com/apache/trafficserver/pull/12905
When an origin sends 100 Continue before a compressible response, `setup_100_continue_transfer()` sets `client_response_hdr_bytes` to the intermediate header size. The subsequent call to `setup_server_transfer_to_transform()` creates the tunnel buffer with `hdr_size=0` - body only, but `client_response_hdr_bytes` is not reset for non-chunked responses. `perform_cache_write_action()` then passes the stale value as `skip_bytes` to the cache-write consumer, causing `ink_release_assert(c->skip_bytes <= c->buffer_reader->read_avail())` to fire in `producer_run` when the response body is smaller than the 100 Continue headers. Fix: set `cache_write_skip` to `0` whenever a transform is present, since `setup_server_transfer_to_transform()` never writes headers into the tunnel buffer.
