This change makes sure that even if the tests are built in a
"release" configuration (with optimizations and NDEBUG turned on),
the assertions won't get compiled out of the tests themselves.
The C standard guarantees that the most recent inclusion of
<assert.h> is the one that counts, so it's important that the
"#undef NDEBUG/#include <assert.h>" come as the last thing in
the block of header files.
"testutil.hpp" includes <assert.h>, so I've left <assert.h> out
of any test that #includes "testutil.hpp", just for the sake of
brevity.
- invalid hostname set to 0mq.is.the.best (naturally!)
- issue happens as other valid-like non-existent hostnames were
redirected by buggy Cable/ISP DNS servers
This allows us to actually report an error to the caller on resolve
failure, rather than asserting later on in the io thread.
