I got the following error:

[…]src/rt/rust_task.cpp:80: void rust_task::delete_this(): Assertion `!borrow_list' failed.

Do you need more information?

[jdm]

There's a rust bug causing the assertion you're seeing, but the main problem is that the font fallback behaviour still isn't foolproof. You can work around this by installing the msttcorefonts package.

[jahfer]

I'm seeing this error on OS X as well. My understanding is that the msttcorefonts are included by default on Mac, so I'm unsure of an easy solution. Suggestions?

[xfix]

I'm seeing this error on Arch Linux too. Installing ttf-ms-fonts package from AUR helped.

[jahfer]

Figured out my issue. I had foolishly disabled all of the MS fonts that were enabled on my system. Re-enabling them all solved my issue. Easy fix.

[nterray]

Is there any hint to allow me to modify the code in order to make the font
fallback behaviour foolproof so that I don't need to depend on the
msttcorefonts?

@caitp, @burg, any further thoughts on the matter?

[jdm]

We improved font fallback behaviour a few months ago.
