Hmm.

Like you, I suspect a compiler bug.  You'd probably need to derive a
smaller example for submission.  Or you could look at the generated
assembly to see if something is out of whack.

If ARM has hardware watchpoints (I don't know), you could debug into
that function and then set a watchpoint on the buffer to find out
exactly where it changes.  You could do this without software
watchpoint as well, it would just be slower.

Reducing the test case may not be easy, unfortunately.  I can give you
a few pointers on things that you might have to include in the new
code if that would help.
