Description Anderson Sasaki 2020-03-24 10:21:05 UTC 
Description of problem:
gnutls-serv --echo exits when a message to be echoed is received.

Version-Release number of selected component (if applicable):
gnutls-3.6.12-1.fc32 

How reproducible:
100%

Steps to Reproduce:

1. Generate server private key and certificate

2. Run the server with ``--echo`` option. For example:

 $ gnutls-serv --echo --x509certfile=cert.pem --x509keyfile=key.pem -p 4433

3. Connect using a client and send a message to be echoed. For example, run:

 $ gnutls-cli --insecure localhost:4433

 Type the message to be echoed.

Actual results:

Server closes connection and outputs:
```
Memory error
```

Expected results:
Server sends a copy of the received message to the client without closing the connection.
