+Subject: [PATCH] tests: test_iffeature_state crash fix
+
+As observed on Debian Trixie RC2, test_iffeature_state crashes due
+to an internal pointer being invalidated.  This invalidation appears
+to be due to a call to lys_set_implemented() possibly causing a
+full recompile of the ctx.
+
+This simply reorders the caching of the path pointers so they are
+not invalidated when used.
