V1.6.12 Windows, When the log is enabled, the broker stops working

[ArielGuille]

The installation of version 1.6.12 for windows works correctly (x32 and x64) as well as manual execution or service. When I enable the log with "log_dest file C: \ temp \ mosquitto.log" the broker stops working. I install version V1.6.10 and the log works ok

I have the same problem on Windows 10 with 1.6.12. Only active settings in mosquitto.conf:

log_dest file C:\Temp\mosquitto.log log_type all

(also tried c:/Temp/mosquitto.log and C:\Temp\mosquitto.log, same result)

Starting the broker from the command line with

mosquitto -c "C:\Program Files\mosquitto\mosquitto.conf"

It seemed to crash the broker. The command returned with no message. Log file gets created but is empty. The directory c:\temp exists and is writeable. If log_dest is commented out, it works just fine. Messages are visible from the command line.

I just got this, using the following on Debian:

  mosquitto:
    container_name: mosquitto
    hostname: mosquitto
    image: eclipse-mosquitto:latest
    ports:
      - "1883:1883"
    volumes:
      - ${HOME}/Mosquitto/Log/mosquitto.log:/mosquitto/log/mosquitto.log
      - ${HOME}/Mosquitto/Data:/mosquitto/data
      - ./mosquitto/mosquitto.conf:/mosquitto/config/mosquitto.conf

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
listener 1883 0.0.0.0
allow_anonymous true

Container starts, creates log file, but no logs. I can fix it by removing the log_dest line.
