gdb logging not working

I am trying to debug a program using gdb. The problem is that no log file appears. Do I need to exit the gdb-session in a specific way or what could be wrong?

Starting gdb and showing logging settings gives this:

Future logs will be written to gdb.txt.

You did not enable logging, enable it with set logging on:

(gdb) set logging on
Copying output to gdb.txt.
(gdb) show logging
Currently logging to "gdb.txt".
Logs will be appended to the log file.
Output will be logged and displayed.
