esp-at crashed when sendind AT commands through socket

[kuhdav]

I compiled and built esp-at project fro ESP32-WROVER platform downloading directly
from github (on the branch master) the sources.

Before building however I ran build.py menuconfig to change the method of
communicating AT command (through sockets instead fo UART)

Then after building and flash the FW, I got the the following log

So far so good, but as soon as I sent an AT command through a TCP client the
FW crashed

I tried several TCP client but result is always the same.
Anybody can help me?
