All,

I ran clang static analyser on tip of git today for x86_64 build. The results are here

Thanks

Any idea why the results are different for arm? Most of the code where
things are reported does not differ by arch.

I think everything reported has been investigated before and found to
be false positives. Do any of them look new/interesting?

ARM is cross compiled using clang itself while x86_64 was using native gcc.
another difference is that arm was using clang 3.8 for static analysis while
x86_64 was using clang 3.7

I did not look into details myself yet, its good to know that nothing new is found
we want to keep it that way
