Hi there:

As for my undersding, it shouldn't work for FreeBSD either.  Your matrix from
vector is not initialized correctly.  Your declaration of 'vector<vector<int> >
mymatrix(n)' only allocated spaces for n vector<int>.  It doesn't say
vector<int> is an array of n integer.  This definitely will cause segmentation
error.
