The crash is in check_digest_auth() which checks the mongoose web server password (if not using 
password protection from the https proxy i.e. apache httpd).

If so you should see this crash on all pages, not just when you access history pages, yes?

Ok, I just checked, my safari is "Version 12.1.2 (13607.3.10)" and I see no immediate crash, even on 
history pages.

But I am macos 10.13.6, maybe that makes a difference.

If you see the safari crash on all pages, then it is not history-specific.

In this case, I would like you to file a bug report on bitbucket "mhttpd crash with safari" and we follow up 
on it there.
