khoih-prog / EthernetWebServer

This is simple yet complete WebServer library for AVR, AVR Dx, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and `ESP8266 ESP8266WebServer` libraries. Ethernet_Generic library is used as default for W5x00 with custom SPI

ESP32 heap corrupting after update to 1.4.0 or 1.5.0 #35

Closed pptsk closed 3 years ago

pptsk commented 3 years ago

Hi, I have finished ESP32 project with your great library, which periodically send json file as response to AJAX request. Wifi and BT are off. Everything works fine, but after update my version 1.3.1 to 1.4.0 or 1.5.0 after each response is free heap memory decreased by 56 bytes until system crash. All is fine with version 1.3.1.

Decoded exception is atached

Hi,

Thanks for using the library and your nice words.

In order to help reproducing the issue, could you post the MRE.

I also noted that you're using experimental ESP32 core 2.0.0-alpha1. Can you try with the stable core v1.0.6 to see if the heap corruption persists ?
