+Subject: [PATCH] tuple: Ensure buf length is always >= 1 in dequote
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If a key is defined with no value, dequote will allocate a buffer with a
+length of 0.  Since the buffer's length is 0, any manipulation of its
+content is UB.
+
+Example .pc file:
+
+prefix=/usr
+exec_prefix=${prefix}
+libdir=${exec_prefix}/lib
+includedir=${prefix}/include
+
+xcflags=
+xlibs= -lSM -lICE  -lX11
+
+Name: Obt
+Description: Openbox Toolkit Library
+Version: 3.6
+Requires: glib-2.0 libxml-2.0
+Libs: -L${libdir} -lobt ${xlibs}
+Cflags: -I${includedir}/openbox/3.6 ${xcflags}
+
+Output using pkgconf 1.5.2 on x86_64 Linux/musl:
+
+% pkgconf --cflags obt-3.5
