Disassembly

RUD stands for “rapid unscheduled disassembly” – a fancy way to say “crashed.”

Across spans of millions of years, mountain ranges tear themselves apart through suicidal erosion. But lately, experts warn, the pace of disassembly has accelerated, stoked by the human-made climate crisis.

If you can trace back through the disassembly to where the variable is first loaded into a register, you can often discover its value or its address by inspecting that register.
