+Subject: [PATCH] test-json: check absolute and relative difference in floating
+ point test
+
+The test fails under valgrind, so there was an exception for valgrind.
+Unfortunately that check only works when valgrind-devel headers are
+available during build. But it is possible to have just valgrind installed,
+or simply install it after the build, and then "valgrind test-json" would
+fail.
+
+It also seems that even without valgrind, this fails on some arm32 CPUs.
+Let's do the usual-style test for absolute and relative differences.
