Bug Description

Per Bothner posted a message on scheme-reports:
  http://lists.scheme-reports.org/pipermail/scheme-reports/2011-July/001142.html
The context is that R7RS probably will have the syntax for self-referential data structures. The expression he posted gives an infinite loop in Ikarus:

Ikarus Scheme version 0.0.4-rc1+, 64-bit (revision 1870, build 2010-11-07)
