[Polyml] Re: ML Basis

That looks great, thank you. I think that should indeed solve everything so far; but it seems that PolyML.export was broken somewhere along the way and now causes Poly/ML to crash (segfault) when calling it. The change happened somewhere between 3b9b3b0 and 3e0f720.

Here's a backtrace from gdb:
