Advanced IP Scanner crashes the FTP server

[bill-orange]

All is well with my use of the FTP server for updating and changing files in my ESP8266 SPIFFS with one exception.

'Advanced IP Scanner' crashes the Ftp server causing a reboot. Here's the exception Decode:

0x400dc503: FtpServer::userIdentity() at C:\Users\William\Documents\Arduino\libraries\esp8266FTPServer-master/ESP8266FtpServer.cpp line 1020

0x40088f75: vPortTaskWrapper at /Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/freertos/port.c line 355 (discriminator 1)

Any advice?

Is this issue still reproducible with up-to-date ESP8266 Core?
I guess, any port scanner can crash the FTP server... it doesn't look stable.
