This isn't a bash bug so this isn't the proper place for your question.
However, what is happening is that the shell evaluates the -d"", removing
the quotes and resulting in -d followed by nothing (so it's the same as if
you had typed -d by itself.
As a result, the delimiter becomes the first character of "odd" and only
one file (even) is pasted.
So
paste -d"" odd even
is the same as
paste even
Try this for comparison:
paste -d"" odd even even
