Five false-positive warning sites caused by GCC 13 losing bound information during aggressive inlining. pxr/base/vt/streamOut.cpp Ensure dimension is less than Vt_ShapeData::NumOtherDims before indexing into shape.otherDims pxr/usd/sdf/schema.cpp Add TF_AXIOM(static_cast<size_t>(level) < std::size(valueTupleDimensions.d)) to the else-if in _AddValuesToValueContext. GCC cannot bound the plain size_t size member but can see std::size(d) == 2. pxr/usd/usd/clip.cpp Add TF_AXIOM(numTimes <= brackingTimes.size()) so GCC can see that numTimes is correctly bounded before std::sort
