Re: firefox dumping core after NetBSD upgrade

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

I wouldn't bother chasing this. My firefox 69.0.2 runs perfectly well
under 9.99.15, so I'd rebuild. You would need rust 1.38 though, my
build failed with 1.37.

There were some rather substantial changes in the last few versions.
