Comment 4 for bug 670088

Good news.
Viva64 gives Free license for the PVS-Studio static analyzer for developers, bloggers and authors of articles in IT subject editions
"Since January, 2011, we announce the new initiative of cooperation with developers of open-source software. We can provide a free single-user 3-month license to any developer or author of articles in IT subject editions/blogs who is interested in the topic of static analysis of C/C++/C++0x source code or who just wants to check his projects and find out if they contain errors our analyzer can diagnose."
Now I use full version of the PVS-Studio. The results is attached (for refactoning branch).
