## Summary This PR intends to make `longjmp` context-switch safe by disabling the interrupts before modifying windowbase and windowsstart to avoid register corruption. This PR is related to an issue first observed on ESP-IDF (https://github.com/espressif/esp-idf/issues/5229) and it was, then, checked on NuttX. ## Impact Prevents `longjump` to load corrupted registers. ## Testing Internal CI build pass considering the `ostest` and `smp` `defconfigs` for ESP32, ESP32-S2 and ESP32-S3. These `defconfigs` enables the `ostest` which run the `setjmp/longjmp` test. Also, the issue was reproduced on NuttX by a test application that performs multiple `setjmp/longjmp` operations (reference: https://en.cppreference.com/w/c/program/longjmp). This test usually crashes and, after applying the patch, the problem is gone. -- This is an automated message from the Apache Git Service.
