[Keno]

I will grab one of the TIG OS X loaners tomorrow and try this out.

[nolta]

Also affects centos 6 & freebsd.

[Keno]

I just saw this on Ubuntu as well for the first time. Will investigate.

[vtjnash]

possibly related to #3880 or #3660

[Keno]

The setfield thing maybe. I think the I found why it spews garbage.

[nolta]

Proximate cause appears to be #3878.

[Keno]

Yeah, I found it. Will have a fix in a second, hold on while I make sure it's ok.

[Keno]

Alright, @StefanKarpinski, I fixed the garbage spewing issue. Probably won't fix the other one, but make sure that issue is fixed for you.

[JeffBezanson]

The build doesn't seem to be failing any more often than usual.

[StefanKarpinski]

Whether because of a fresh terminal or changes since last night, I no longer have tests spewing garbage or dying.
