+  We want to check that we have a DIE describing the typedef t like this:
+
+	.uleb128 0xc	# (DIE (0xb8) DW_TAG_typedef)
+	.ascii "t\0"	# DW_AT_name
+	.byte	0x1	# DW_AT_decl_file (../../prtests/test.cc)
+	.byte	0xb	# DW_AT_decl_line
+	.long	0x78	# DW_AT_type
+
+  e.g, it should not haven any child DIE -- the bug here was that this
+  DIE had children DIEs. So we check that the last line is immediately
+  followed by a line containing the pattern "(DIE (", instead of a
+  line containing a DW_AT_sibling attribute.
