Hi, I added unittest-release builds into Travis. LDC works well but DMD fails in few places. One DMD bug was filled [1]. I will explore others when this is fixed. Please use only LDC for builds with O flag for now. [1] https://issues.dlang.org/show_bug.cgi?id=17943 Best regards, Ilya

Well, that site does say that it's using 2.072.2, which is rather old, and it gives no indication as to whether it's compiling with -O. I just tried it on my local 64-bit FreeBSD box with dmd master, and it fails if I compile with -O but succeeds if I don't compile with -O, which is exactly what the bug report states.

It fails for me on OSX for old 2.072 too. Looks like it depends on how DMD was configured and compiled.
