+/* TODO(sergey): This is rather nasty bug happening in here, which

+ * platform indipendent workaround. Also even if it's a compiler
+ * issue, it's not so simple to upgrade the compiler in the release
+ * environment for linux and doing it so closer to the release is

+ * For this release it's probably safer to stick with such a rather
