Added dead command to trace
including: bitwise operations variable size arrays dereferencing dead objects dynamical objects input enumeration (trace backtracking)
Avoid crash from infinite array size

I'm generally in favour of omitting the "default" clause when all cases are covered, so as to let the compiler warn about this. But that view isn't necessarily shared by others.
That said: the placement of { and } does not match coding guidelines.

No need to use "inline" within class definition.

Use cstring, not string.h

At some point it was agreed to use American English across the code base, so please use "initialize".

So the first error will be caught, but further errors won't?

You may just want to use has_prefix(...) instead of this function

Should this be fixed right away?

I don't understand those changes.

The root object need not be a symbol - it could, for example, be an array. Use object_descriptor_exprt to compute the root_object().
