Add correct offset for end of chunk

Using &current->chunk_ + x will add x * sizeof(current->chunk_) to the pointer, but we only want to add x.

Adding a much larger number still "works" on 64bit systems (although it does not perform the intended check). However on 32bit platforms this wraps (at least in the way used by sllisttest.cc) and the "end" of the chunk is suddenly before the beginning.

Closes #57 (closed)

@markus.blatt As you wrote the failing debug check, could you take a look at this?

Well, I agree that your commit fixes a problem. But I do not see that your description is correct.

What we want to test is that b is in some chunk current (current->_chunk_<=b< current->_chunk_+chunkSize). This should be a pointer comparison. Taking the address of a pointer is surely nonsense and I should be embarassed.

Nice catch!

Now I get it. We were not taking the address of a pointer but dereferencing the pointer and that is a statically size array.

Sorry for being dense. Approved.
