I'm guessing something wonky happened during the build. Abort during file write, perhaps?

Can you reliably reproduce this? If not, I'm tempted to WORKSFORME.

It was the first time I was trying to use mach on this machine. I did clobber before attempting to build.

The problem was the mozinfo.json file in the top level source directory.
