I haven't updated to your latest yet. When I had commented that line
out, the errors persisted for me. They went away when I realized that
CRC32_Init() is indeed not thread-safe the very first time it's called
in a program (it was not meant to be thread-safe when written!), and
added "#pragma omp critical" right before it. I find it weird if/that
we were hitting this very thing. Yet I am not getting any faults with
that change, running a command almost identical to yours. ;-)
