Any recommendation of a good static source code analyzer for C++ ?

PVS Studio has always seemed to catch the most errors for me. It is by far worth the price if you s/w is at all important to you. But no tool is perfect. I also run cppcheck, Microsoft's VS (never liked that one much).

Haven't tried Clang because I am on Windows for my C++ stuff.

Yes, seems to be working now for me as well.

Sorry, that was a typo. Unfortunately I can't seem to figure out how to edit the title post-submission.
