2.4-rc2 crash while connecting to WPA2 Enterprise (Eduroam)

Hi,

I try to connect the ESP8266 with eduroam with the new 2.4-rc2 (build d1e8fe99a23c0e4641199f7a5ee3b0b8ca334443) Arduino lib pulled via git as in the descriptions. The code connects to Eduroam as I can see connections results in our university log (only one line, sorry no output of log from radius). At some point, I get a crash and an error stack. I paste the code and the error stack below.

#include

extern "C" {
#include "user_interface.h"
#include "wpa2_enterprise.h"
}

// SSID to connect to
char ssid[] = "eduroam";
char wlpasswd[] = "";
char username[] = "--------------------";
char identity[] = "------------------";
char password[] = "-------------";
char new_password[] = "-----------";

const char* host = "ipinfo.io";

void setup() {
Serial.begin(115200);
delay(1000);
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);

WiFi.mode(WIFI_STA);

wifi_station_set_wpa2_enterprise_auth(1);

// Clean up to be sure no old data is still inside
wifi_station_clear_cert_key();
wifi_station_clear_enterprise_ca_cert();
wifi_station_clear_enterprise_identity();
wifi_station_clear_enterprise_username();
wifi_station_clear_enterprise_password();
wifi_station_clear_enterprise_new_password();

wifi_station_set_enterprise_identity((uint8*)identity, strlen(identity));
wifi_station_set_enterprise_username((uint8*)username, strlen(username));
wifi_station_set_enterprise_password((uint8*)password, strlen(password));
wifi_station_set_enterprise_new_password((uint8*)new_password, strlen(new_password));
//wifi_station_set_enterprise_ca_cert(ca_pem, ca_pem_len);

WiFi.begin(ssid, wlpasswd);

while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print(".");
}

Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}

void loop() {
delay(5000);

Serial.print("connecting to ");
Serial.println(host);

WiFiClient client;
const int httpPort = 80;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}

client.print(String("GET ") + "/ip" + " HTTP/1.1\r\n" +
"Host: " + host + "\r\n" +
"Connection: close\r\n\r\n");
delay(500);

while(client.available()){
String line = client.readStringUntil('\r');
Serial.print(line);
}
return;
}

The console result reads:
