HTTPClient crash on GET() for url with 1 redirect

[cpainchaud]

Hardware:

Board: ESP32 Dev Module
Arduino IDE Version : 10805
ESP SDK version: v3.3.4-432-g7a85334d8
IDE name: PIO
Flash Frequency: 40Mhz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Windows 10

Description:

Crash happens when downloading URL with http.setFollowRedirects(followRedirects_t::HTTPC_STRICT_FOLLOW_REDIRECTS);
This URL indeeds forward the client once to the read URL where the binary file is.
Note that the crash does not occur if I give it the relocated URL directly.

Sketch: (leave the backquotes for code formatting)

void setup()
{
  Serial.begin(115200);
  delay(10);

  WiFi.config(IPAddress((uint32_t) 0), IPAddress((uint32_t) 0), IPAddress((uint32_t) 0));
  WiFi.begin("my_network", "my_password");
  WiFi.setAutoConnect(true);
  WiFi.setAutoReconnect(true);
  Serial.println("wait a bit for Wifi to be up");
  delay(10000);

  HTTPClient http;

  Serial.println("Requesting web page now!");

  http.setFollowRedirects(followRedirects_t::HTTPC_STRICT_FOLLOW_REDIRECTS);
  http.begin("https://github.com/cpainchaud/RFLink/releases/download/nightly/esp32-firmware.bin");
  int httpCode = http.GET();


}


void loop()
{

}

I know that PIO can use the development version of this repo. Please check in their docs how to do it and try against that. I added a fix exactly for redirects

platform = https://github.com/platformio/platform-espressif32.git should do it, i will give it a try !

There was something weird so I decided to wipe .pio and PIO's framework directory to ensure it was not mixing frameworks parts... and i am afraid it's really not fixed

Took me a while but I figured it out :) fixed in the commit above
