FreeBSD ccall failure

[StefanKarpinski]

Examples:

• https://freebsdci.julialang.org/#/builders/1/builds/11427
• https://freebsdci.julialang.org/#/builders/1/builds/11292
• https://freebsdci.julialang.org/#/builders/1/builds/11452

Seems to be getting more frequent perhaps?

We should change that read call to pass stderr= stderr , so we can learn what failure occurred.

I've been running the ccall tests 100 times in a loop on FreeBSD 11.2 (note that the CI machines are running 11.1) trying to reproduce the failure but no luck thus far.

@iblis17, have you managed to reproduce this at all?

Looks like this hasn't happened in a long time, so I'm going to close.
