Enable heap poisoning features to detect heap corruption caused by out-of-bounds access to heap memory.
|

See the "Heap Memory Debugging" page of the IDF documentation
|
|
for a description of each level of heap corruption detection.

Enables the heap tracing API defined in esp_heap_trace.h.
|
|
|
|
This function causes a moderate increase in IRAM code side and a minor increase in heap function
|
|
(malloc/free/realloc) CPU overhead, even when the tracing feature is not used.
|
|
So it's best to keep it disabled unless tracing is being used.

Number of stack frames to save when tracing heap operation callers.

More stack frames uses more memory in the heap trace buffer (and slows down allocation), but

can provide useful information.

Enables tracking the task responsible for each heap allocation.

This function depends on heap poisoning being enabled and adds four more bytes of overhead for each block

allocated.
