  I took a quick step through it in the debugger.  It's possibly an
excess-precision FP thing.  Can you point me at what code in the gfortran

All these years I've been working with the apparent misconception that gnu compilers left these at hardware/OS default, with the possible exception of -ffast-math which should attempt to set abrupt underflow for SSE.
