Moreover, I've seen many Delphi code snippets out there (e.g.
http://www.cs.wisc.edu/~rkennedy/array-delete) rely on reference counting
behaviour.
Great. I once wrote code that relied on Turbo Pascal's heap list structure
internals.
Shall I post a bug
Florian Klaempfl:
FPC and Delphi handle code generation for ref. counted types slightly
different, so there might be cases where the ref. counter differs. As
long as
there is no memory leak when the vars are properly used, we
don't
consider it as a bug.
I see, well, there should be

The reference counting logic is considered to be an opaque implementation
detail (whose implementation can change at any time). It is undocumented by
design.

In fact, it was already documented in detail in FPC Language Reference Guide:

And the last one explicitly states No assumptions should be made about the
number of temporary variables or the time when they are finalized.
I see, thanks Jonas for noting that statements.

I found that the last element of a dynamic array starts with reference count =
2 in FPC, but in Delphi is 1. Is this an FPC bug, or FPC implements reference
counting differ from Delphi?
