Steps to reproduce.

红外线学习在创建线程的时候会把这个栈变量的指针传递给线程，但是栈会释放的，线程里面访问的时候就会导致panic,我修改成全局变量后就不会panic了，我是按照例程写的，不知道是不是我的程序有问题

ir_learn_common_param_t learn_param ;

esp_err_t ir_learn_new(const ir_learn_cfg_t *cfg, ir_learn_handle_t *handle_out)
{
    ESP_LOGI(TAG, "IR learn Version: %d.%d.%d", IR_LEARN_VER_MAJOR, IR_LEARN_VER_MINOR, IR_LEARN_VER_PATCH);

    BaseType_t res;
    esp_err_t ret = ESP_OK;
    IR_LEARN_CHECK(cfg && handle_out, "invalid argument", ESP_ERR_INVALID_ARG);
    IR_LEARN_CHECK(cfg->learn_count < IR_LEARN_STATE_READY, "learn count too larger", ESP_ERR_INVALID_ARG);

    ir_learn_t *ir_learn_ctx = calloc(1, sizeof(ir_learn_t));
    IR_LEARN_CHECK(ir_learn_ctx, "no mem for ir_learn_ctx", ESP_ERR_NO_MEM);


        learn_param.user_cb = cfg->callback;
        learn_param.ctx = ir_learn_ctx;

下面创建这个线程的时候会将栈变量的指针做完参数传递给线程，这应该是有问题的

        res = xTaskCreatePinnedToCore(ir_learn_task, "ir learn task", cfg->task_stack, &learn_param, cfg->task_priority, NULL, cfg->task_affinity);

上述的描述可能不够清晰,下面的描述更简洁

问题描述

在 [components/ir/ir_learn/ir_learn.c:555] 处，函数 ir_learn_new 创建线程时传递了栈变量的指针给新线程，这会导致未定义行为。

具体代码位置如下,learn_param是函数栈上的变量

    if (cfg->task_affinity < 0) {
        res = xTaskCreate(ir_learn_task, "ir learn task", cfg->task_stack, &learn_param, cfg->task_priority, NULL);
    } else {
        res = xTaskCreatePinnedToCore(ir_learn_task, "ir learn task", cfg->task_stack, &learn_param, cfg->task_priority, NULL, cfg->task_affinity);
    }
}
