Some toolchains (in this case referring to a g++ 4.9, or "arm-linux- androideabi-g++ (GCC) 4.9 20140827 (prerelease)" according to my --version, from the Android NDK r10e-rc4 and potentially with custom patches; others may be affected as well) fail to prove that myVec in WebRtcIsac_CorrelateInterVec is never used uninitialized. This is likely due to the compiler thinking the assignment in line 468 might not happen. Changing the loop condition in line 466 to rowCntr < SOME_CONSTANT also helps, suggesting that the compiler can't infer that there are only 2 values interVecDim can have at that point, and neither of them are 0. Of course, this is not an acceptable fix, as it changes behaviour. This seems to be a compiler bug, or at least an issue with its heuristics. However, we can't really change toolchains at the moment, and ultimately this change improves support for certain older compilers.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.
Development
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
