No progress on that. The team hasn't had the bandwidth to work on it.
However, I'm less suspicious of the toolchain now. I built with a couple of
different compiler options and a couple of different versions of the toolchain,
including the C library that runs in production. In all cases, I see the same
result.
Any chance the problem is in the test itself (e.g., some sort of undefined
behavior or a 64-bit vs 32-bit difference)?
Thanks,
Taylor
