Intermittent Travis build failure?

[simonster]

See here from #14703. The error is:

fatal error during bootstrap:

(parse-error "read: unexpected ']'")

Given this is happening while building inference0.ji and that PR only touched linalg code, I don't think my changes could cause this...

Thanks for openning an issue for this. IIRC, this happens mainly on travis linux although I've also seen it happen a few times on travis osx (before we disabled it). I haven't got any luck reproducing it locally. The time it starts to happen is around when we switch to the new travis setup.

Yes, I've seen this a few times too.

Likewise #14702 (comment)

Is anyone doing make -j3 install locally, with deps in place but none of src built yet? I think it's a race condition while both release and debug system images are building in parallel.

[eschnett]

@tkelman I confirm this has been problem for some time; I have to do make -j8; make -j8 install to build. I haven't figured out where the conflict is, though -- sorry.

I guess it's probably julia_flisp.boot... The first travis log linked even has a compiler warning about ignoring null characters.
