Part of the refinement to get the test to fail faster was changing the _W
operand from 64 to 32-bits, which also eliminated the use of the neon/vfp
registers. You can see the revised disassembly here:

i can exclude neon code for dd-wrt in dropbear if it helps. but would be
greater to nail down the problem. otherwise other programms would be
likelly affected too

As a postscript, I was able to refine the logic to produce the corrupted result
almost instantaneously. I'm also able to get it to fail with an all-zero input
dataset and a bitwise OR operation instead of the original squaring
multiplication operations, which allows me to see what actual corrupt
