ExtFS crashes OSX when working with Ext4

This is driving me crazy,

I'm using ExtFS to work with Ext4 disk images on a MAC running High Sierra 10.13.3. Every sixth or so time I mount, write and unmount the file system the whole OS crashes!

All have to go on the Apple crash report below.

Can anyone help?
