about

nx_jpegmem_probe.nx -- INSTRUMENT: does nx_jpeg_decode_rgb overrun/leak per call? Decodes the SAME jpeg N times in one process, printing VmRSS after each decode, freeing the caller-visible RGB each round. A flat RSS = the lib cleans up; a climbing RSS = per-call arena growth (the OOM suspect for the 12-decode toon run); ARENA-OVERRUN lines localize the write. usage: nx_jpegmem_probe <file.jpg> <rounds>
