+Subject: [PATCH] Avoid integer overflow
+
+pinpoint is affected by a possible integer overflow, that was also
+found and patched upstream in gtk+
+https://git.gnome.org/browse/gtk+/commit/?id=894b1ae76a32720f4bb3d39cf460402e3ce331d6
+
+With g_malloc_m we can avoid the integer overflow.
+
+As pointed out by Pacho Ramos in
+https://bugzilla.gnome.org/show_bug.cgi?id=762029
