I can confirm this compiles now and the previous segfault during test execution is gone. Tests however still fail in this branch and something also hang. Example test output:

[----------] 1 test from Timeouts
[ RUN      ] Timeouts.VelocyStream
/home/jsteemann/Downloads/fuerte/tests/test_connection_timeouts.cpp:59: Failure
Value of: wg.wait_for(std::chrono::seconds(3))
  Actual: false
Expected: true
[  FAILED  ] Timeouts.VelocyStream (3103 ms)
[----------] 1 test from Timeouts (3103 ms total)

[----------] 1 test from RequestTimeout
[ RUN      ] RequestTimeout.HTTP
/home/jsteemann/Downloads/fuerte/tests/test_connection_timeouts.cpp:57: Failure
      Expected: e
      Which is: 2-byte object <50-04>
To be equal to: fu::Error::Timeout
      Which is: 2-byte object <EB-03>
(hangs)

Until that point, ASan does not report any errors during the tests.
