I've got a couple seemingly strange problems that are popping up. First off, when compiling with -unittest, I get a linker error: Error 42: Symbol Undefined _D4vibe4core11concurrency3CLS7__ClassZ. Note that I am trying to build the first example on the docs page.
Second, even when building and running the very minimal example on the main page, I get another error: Got exception while accepting new connections: Assertion Failure. This happens with less trivial examples as well, which causes pages to not render and long strings of errors to be printed in the console.
