Hi Hans,

Sorry you're stuck in Windows.  Updated core-reg.tex attached.

Short answer: No.

Long answer: A substantial test file is needed to demonstrate all
the page collapsing problems.  I do not have time to produce a
public domain test.  I have tested it on a 35-page document which
is not releasable.  On that document it fixes the all of the known
bugs and does not break register placement when compress is off.

Here is a part of a register placement from the 35-page document.
The item names have been changed.
