More often than not, the tools submodule (https://github.com/D-Programming-Language/tools) will not build on git master. So I'm wondering whether it's even being tested before pushing commits.

The error I have now is with ddemangle:

std.md5 is scheduled for deprecation. Please use std.digest.md instead

phobos/std/regex.d(6706): Error: template D main.__lambda3 does not match any function template declaration. Candidates are:

ddemangle.d(57): ddemangle.main.__lambda3(__T2)(a)

(this is the line: writeln(replace!((a) => demangle(a.hit))(line, r));)
