CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE

I write code for ESP32 but with serial I often see that it crashes. My memory is bad and sometimes may forget to allocate space for a pointer I strcat repeatedly ==> crash!

My question is if it does crash, by defualt, will an ESP32 revert/rollback to last-known-good partition?

Or does CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE need to be set in IDF kConfig?
