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