It runs out of stack space here, dumping out "Widows:1"... Reporter: I guess you don't have any ulimit on stack size?

I did not have any ulimit set. When I do restrict the process virtual memory size, I get a segfault. So I think that the same thing is happening. It's just that in your system it terminated after running out of stack space, whereas on mine it just kept consuming system memory.

Here's another case. This one's a very simple page. http://llvm.cs.uiuc.edu/docs/Stacker.html I was able to print two very similar documents from the same documentation set even though they were longer.
Same problem occurs on http://www.rtd-denver.com/Routes/Route16/016Weekdays.html (kde 3.5.0 on i386 centos 3.6)
