Re: Starting build-system work (Windows/Mac users please speak up)

I am now redirecting the output of the scripts to a file and trying to
filter using grep. I discovered that passing the -Xcheck:jni flag not
crashes travis but also the PostgreSQL database. Below is the postgres log
output. Can you shed some light on this?
