Please note, that the information is only about what gets actually compiled, code disabled by #if .. #endif is not considered (e.g. when determining whether a variable assignment is useless). There are probably some false-positives.
I used scan-build/clang 4.0.
Enjoy
We much prefer if emails to bugs are self-contained and not pointing to some random web URL which cautious people aren't going to follow. It would also be helpful to actually state in your own words what you believe the bug is/what the correct behavior should be.
