Thanks for your answer. I used dmd 2.051 which is still my system 
default due to compatibility issues (deprecated methods etc.). It 
didn't occur to me that it's (hopefully) the compiler version, 
especially because I saw the code snippet in process.d and didn't 
know it was a recent fix. I'll try the latest version.
