the error message you encountered means that transformation of displacement
from internal coordinates to cartesians failed. This is rather unusual situation,
especially for a bond length type variable.

This problem could be caused by the ill-defined Z-matrix.
Could you please send me your complete input file for some experiments?

All the best,
Alex
