Hi Piotr,

This issue occurs copy and pasted in two other locations as well:

    examples/ip_pipeline/pipeline/pipeline_common_fe.c
    1295:           n_cmds * sizeof(cmdline_parse_ctx_t *));

    examples/ip_pipeline/thread_fe.c
    340:            n_cmds * sizeof(cmdline_parse_ctx_t *));

    examples/ip_pipeline/init.c
    1475:           n_cmds * sizeof(cmdline_parse_ctx_t *));

Perhaps you could fix those in the same patch.

Thanks,

John
