Enabling this option compiles all IDF C++ files with exception support enabled.
Disabling this option disables C++ exception support in all compiled files, and any libstdc++ code which throws
an exception will abort instead.
Enabling this option currently adds an additional 20KB of heap overhead, and 4KB of additional heap is allocated
the first time an exception is thrown in user code.

FreeRTOS has the ability to store per-thread pointers in the task

``NULL`` pointer as the deletion call back. This results in the selected Thread
Local Storage Pointer to have no deletion call back.
In IDF the FreeRTOS thread local storage at index 0 is reserved and is used to implement
the pthreads API thread local storage (pthread_getspecific() & pthread_setspecific()).
Other indexes can be used for any purpose, provided
:ref:`CONFIG_FREERTOS_THREAD_LOCAL_STORAGE_POINTERS` is set to a high enough value.
