#                   Confirmed bug on WI-T4.0.0.469, got:
#                      arithmetic exception, numeric overflow, or string truncation
#                      -string right truncation
#                      -expected length 75, actual 264
#                   Checked on WI-T4.0.0.470 - works fine.
