levmarq.cc is in progress but in levmarq.cc there is a non deterministic crash in lines 309-339.

My assumption is that the pointers used by Subs::Array1D e.t.c are not safe particularly with the tparam=centre copy. I think this goes deep into subs including Subs::Buffer1D.

Here is the output to two consecutive runs of the code from the section outlined above:
