The output is wrong because I typo'd in my cut-and-paste in the code. This
doesn't affect the bug, just the message.
Attached is a fixed version, and the output really looks like:
bit_vector_rol_ror_bug.vhdl:20:3:@0ms:(assertion warning): ror 5 is broken
bit_vector_rol_ror_bug.vhdl:28:3:@0ms:(assertion warning): rol -5 is broken
