Description Chris Jones 2001-08-17 10:52:05 EDT
Description of Problem:
Using ghostscript to distill postscript produced by Windows/Adobe 
Postscript printer drivers, I've found that some documents cause 
ghostscript to enter some kind of race condition where it consumes 100% 
CPU without actually appearing to do anything useful.

Version-Release number of selected component (if applicable):
ghostscript-5.50-17

How Reproducible:
I can provide a document that will tickle this bug, however, I am not able 
to post it publically because it contains private information. I will be 
happy to send the document to whomever is assigned this bug.

Steps to Reproduce:
1. 
2. 
3. 

Actual Results:


Expected Results:

Having checked with our legal eagles I'm sad to report that I can't even send 
the document privately because of the UK Data Protection Act.

I'm going to play around with it and see if I can remove the private data and 
still reproduce the bug, failing that, what can I do to provide you with enough 
information to be able to investigate?
Comment 2 Crutcher Dunnavant 2001-09-25 12:03:21 EDT
This is not surprising. PostScript is a production language, and as such, is
succeptable to the halting problem. Some documents don't ever finish. A brief
example follows:


%!PS-Adobe-2.0
/loop { 1 add dup == loop } def
1 loop


Without an example document which _should_ finish, but does not, I am closing this.
