Will this setup a signal handler in a Release+Asserts build?
That is not very nice, a library shouldn't setup signal handlers, except
in debug mode.

Isn't there a better macro to differentiate between Release and Debug

Or to allow the library's client to specify whether it wants the signal
handler or not?
That would be similar to how the PrettyStacktrace stuff works: client
software can skip it completely when in release mode,
and still have assertions enabled.
