Details of which pointer is not aligned.
Details of why a pointer had to be in-bounds.
Error information for when the program we executed turned out not to actually be a valid
program. This cannot happen in stand-alone Miri, but it can happen during CTFE/ConstProp
where we work on generic code or execution does not have all information available.
Error information for when the program exhausted the resources granted to it
by the interpreter.
Error information for when the program caused Undefined Behavior.
Error information for when the program did something that might (or might not) be correct
to do according to the Rust spec, but due to limitations in the interpreter, the
operation could not be carried out. These limitations can differ between CTFE and the
Miri engine, e.g., CTFE does not support dereferencing pointers at integral addresses.
