    Description

      Steps to reproduce:
      Execute mariadb-backup.exe from a command line

      Result: The tool crashes with a crash report, Stack Trace with debug symbols and crash dump are attached.
      Other than that, basic operations (backup/prepare/restore) work without problems.

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
       
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.
       
      Server version: 10.5.6-MariaDB
      key_buffer_size=0
      read_buffer_size=131072
      max_used_connections=0
      max_threads=1
      thread_count=0
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 5337 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      Attempting backtrace. You can use the following information to find out
      where mysqld died. If you see no messages after this, something went
      terribly wrong...
      ucrtbase.dll!strcmp()
      mariadb-backup.exe!get_defaults_options()[my_default.c:293]
      mariadb-backup.exe!my_load_defaults()[my_default.c:419]

      ntdll.dll!RtlUserThreadStart()
      The manual page at https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mysqld/ contains
      information that should help you find out what is causing the crash.
