Self-signed certificate HEAP memory issue

[alexair777]

hi there,

I tried the code self-signed certificate based on the fork: (https://github.com/jackjansen/esp32_idf5_https_server) on a ESP32s3.

Using a keysize of 1024 bit leads to the following error:
assert failed: heap_caps_free heap_caps_base.c:63 (heap != NULL && "free() target pointer is outside heap areas")

Using it with a keysize of 2048 bit leads to the following error:
CORRUPT HEAP: Bad tail at 0x3fcecc00. Expected 0xbaad5678 got 0x3fceca88
assert failed: multi_heap_free multi_heap_poisoning.c:276 (head != NULL)

What is the reason for this issues?
I checked the free heap memory (heap_caps_get_free_size(MALLOC_CAP_DEFAULT)) before starting new SSLCert() and it says: 337316
I can't get this example running properly until the ESP crashes.

It is interesting, when I am changing the keysize to 1023 bit or 2047 bit the following message occurs without heap error:
Cerating certificate failed. Error Code = 0x04, check SSLCert.hpp for details

Thank you very much for your help!
