posts_per_page causing infinite duplicate content

[firebird75]

While using the posts_per_page in the pre_get_posts, if you set it to -1. It will output all the posts. The issue is that if you use this with the main query on a taxonomy archive page, then it will create unlimited number of subpages with all the same content as the main page :
taxonomy-1/
taxonomy-1/page/2/
taxonomy-1/page/3/
...
taxonomy-1/page/500/
etc...

It is probably not really the expected behavior...

The same applies to all other types of archive pages - year, month, day, author.
