   6 >Release:        LaTeX2e <1999/12/01> patch level 1
   7 >Environment:
   8  Hyphenation: standard
   9  \@TeXversion: undefined (Standard setting for TeX3.141 and later)

  12 >Description:
  13 Description of bug:
  14 For the first argument of \ifthenelse \pageref has to be
  15 redefined, in order to make it expandible. But the
  16 redefinition of \pageref does also have an effect in the
  17 second and third argument of \ifthenelse. Here \pageref
  18 should have its normal meaning.
