These issues listed below are known to be current and are expected to be addressed.
The function in BinaryArith fifteenOrLess4Four is known to not be currently
thread safe. Therefore set NTL's thread pool to 1 to avoid this issue. The
function NTL::SetNumThreads can be used to set the number of threads in the
pool and NTL::AvailableThreads gives the current available threads in the
pool.
