    Fix bug in OpenMP parallelization. · 0b5acd3b
    Steffen Christgau authored and Matthias Rüster's avatar Matthias Rüster committed
    m is declared outside the parallelized for-loops which makes it shared
    by default according the OpenMP standard as well as by the
    "default(shared)" statement.  This implies a race condition and the
    actual value of m is undefined with in the loops.  The patch fixes this
    Note that the compiler might not allocate storage for m on the stack and
    use register instead, so the race condition may not manifest in wrong
    output when optimization is enabled, but the error is present anyway.
