Out of curiosity, which features are those?

*More* frequently?  You mean older nanos used to crash too, now and then?
If yes, which nanos?  All versions since 2.7.0?

Nano itself does not come with a syntax file for Markdown.  Please attach
the file that you use for this.  Maybe it contains regexes that trigger the
segfault.

> What can I do to track this down?

Try to recreate the exact situation of the crash as soon as you get a
segfault: open the same file again, type the same stuff again, until
you can reproduce the crash.  Once you can reproduce it, it can be
fixed.

No.  But I have gotten into the habit of pressing ^S now and then.
That key is bound to "savefile" by default since 2.9.0.
