2. From this Terminal window start Sync the way you usually do.

3. When Sync crashes, there should be a crash dump placed near rslsync binary. It will be a file with digits in its name. NOTE: if you launch Sync at startup via a startup script, dump will be placed in another directory, depending on your script, being most likely file system root.
