I've pushed a number of changes to the merge-2.071 branch, with the result

- appveyor Windows x64 passes
- appveyor Windows x86 fails for the same test as master, but I cannot 
reproduce it locally
- travis OSX passes
- travis/circleCI linux fail for 1 unittest, and crash for 2 more

I tried to reproduce the latter in a VM with Ubuntu 16, but also got 
failures for the master branch. Are there known issues with special 
configurations? I'm building with LLVM 3.7.1 and LDC 0.17.1 based on DMD 
2.068.2 and LLVM 3.8.0.

What's left is catching C++ exceptions, which is only expected to exist 
for linux/64. I have no idea what to do about this, but could probably 
implement it for Windows instead ;-)
