  Hello,

referenced_type_should_be_emitted should not crash on types with
associated translation unit, like e.g, "void type".

Fixed thus.

	* src/abg-writer.cc (referenced_type_should_be_emitted): Don't
	crash on types with no associated translation unit.

Signed-off-by: Dodji Seketeli <dodji@redhat.com>
Applied to master.
