--- Comment #12 from alex.jercai...@gmail.com --- Also, on FreeBSD 12 I could not build phobos or druntime with the most recent compiler, due to segfaults while compiling barrier.d. I could however build both druntime and phobos with the one here[1]. I think these problems are related. [1] - http://downloads.dlang.org/releases/2.x/2.076.1/dmd.2.076.1.freebsd-32.tar.xz --
