+Subject: decode: avoid using a static buffer in th_get_pathname()
+
+decode: avoid using a static buffer in th_get_pathname()
+
+A solution suggested by Chris Frey:
+https://lists.feep.net:8080/pipermail/libtar/2013-October/000377.html
+
+Note this can break programs that expect sizeof(TAR) to be fixed.
