etc/valgrind-root.supp

+# Additional valgrind suppression file for ROOT.
+#
+# To use, run valgrind with:
+#   valgrind --suppressions=$ROOTSYS/etc/valgrind-root.supp ...
+#
+# This file suppresses known and expected / inevitable valgrind
+# reports, e.g. due to ROOT's runtime type information that must
+# survive until the end of the process and thus leaks.
+# It only suppresses leaks, and a few errors generated by X11.
