This is driving me crazy,

I'm mounting, reading, writing and unmounting an Ext4 disk image via the command line. The whole operation happens in ~4 seconds. Every fourth or fifth time I do this the OS crashes with the below report.

This is on an MacBook Pro running High Sierra 10.13.3.

I don't want to buy ExtFS until I know it's reliable. Anyone had this issue before?
