Description
When debugging often it doesn't matter on what combination bug reproduces and you don't need to run test with all the combinations. So currently you have to know how combinations are named and explicitly specify one.
--one-combination option selects first combination for the test in alphabetical order
--list-combinations shows the list of existing combinations for the specified test with easily selectable form like this:
$ mtr --list-combinations versioning.foreign
|
Combinations for versioning.foreign: timestamp,trx_id
|
versioning.foreign,timestamp
|
versioning.foreign,trx_id
|

Don't print hints:
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.

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.

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.

Output from gdb follows. The first stack trace is from the failing thread.

The following stack traces are from all threads (so the failing one is

duplicated).

Besides the option non-debugger backtrace should not be printed if debugger backtrace was successfully printed.
The above options should be accumulated into one option --quiet-devel (or something like this).
