Occasional Contributor***** PROBLEM SOLVED!! *****
Problem was traced to the project using the ALTLVDS_TX macrofunction without setting the output pins to LVDS. In the Terasic Cyclone V GX Starter Kit all LVDS-capable outputs are assigned to be "2.5 V" in the QSF file -- close but not quite there!
It would be nice if this issue was caught before crashing the assembler (say, in the Fitter).
