Bug#548825: texlive-latex-base: \pdfinfo with hyperref should not have undefined behavior



Control: tags -1 - fixed-upstream

Hi,

the issue has been forwarded upstream and the issue been closed w/ the
following comment:

I think I'll close here, interaction with direct use of the primitives
is largely undefined and this whole area is likely to get looked at
again with the expl3 backend code.

Therefore the tag fixed-upstream is not correct, I remove it.
