ESP32 gets hanged in Cache_Flush() when partition API's called (IDFGH-6272)

Environment

Development Kit: [ESP32-Wrover-Kit]
Kit version (for WroverKit): [v1|v2|v3|v4]
Module or chip used: [ESP32-WROVER-I]
IDF version (run git describe --tags to find it): v4.3.1-3-gc5f29dd524
Build System: [Make|CMake|idf.py] ---> Cmake but through BAzel Build TArget, this is the difference but have made sure to follow the complete cmake process, ld files, flags. No difference found while building through bazel
Compiler version (run xtensa-esp32-elf-gcc --version to find it): xtensa-esp32-elf-gcc (crosstool-NG esp-2021r1) 8.4.0
Operating System: [Linux|
Using an IDE?: [No]
Power Supply: [USB]

Problem Description

IF app_main() task running with the default priority=1, then NO partition API works and the crash appears at Cache_Flush(0); in the file flash_mmap.c -> spi_flash_mmap_pages() If WDT is enabled then WDT resets the device with reset reason as TG1WDT_SYS_RESET and repeats this in a continuous reset loop

Expected Behavior

The esp32 should not get crash while doing Cache flush

Actual Behavior

The device goes in the hanged mode or resest if WDT enabled when Cache_Flush is called while calling partition API from App layer

Code to reproduce this issue

Simple code in blinky app,just before blinky app's while 1 loop starts, added partition usage API's. This will work in the espidf scenario, However, I am using the Bazel build system to simulate exactly same steps as Cmake does, Able to debug and pinpoint the issue at the file flash_mmap.c ----> spi_flash_mmap_pages() --> Cache_Flush() Also in the debug window nothing can be seen about the esp internals, debugging control goes missing, Program counter doesn't show up in the call stack

// the code should be wrapped in the ```cpp tag so that it will be displayed better.

ESP_LOGE(TAG, "Partition table API");
const esp_partition_t* partition = esp_ota_get_running_partition();   -----> Inside this when CachE_Flush(0) is called from spi_mmap_pages() crash/reset occurs
  if (NULL != partition) {
    ESP_LOGE(TAG, "load partition table entry 0x%x", (intptr_t)partition);
  }
   esp_err_t next_update_partition = esp_ota_set_boot_partition(esp_ota_get_next_update_partition(NULL));
   if (ESP_OK == next_update_partition) {
     ESP_LOGE(TAG, "Set Boot Partition table entry 0x%x", (intptr_t)update_partition);
  }
While(true){
  blinkLeds(); 
}
