This is not a requirement of POSIX (which doesn't even have ctors), but it's a reasonable expectation we currently get wrong and I think it might be specified in ELF or some related sysv "standards".
It is part of the ELF 1.2 standard and is not only required by GLib, but also Nouveau, gtk-doc, some Qt apps, and others.
