> When I try to print to PDF, some cairo assertion fails and aborts the program
This does seem to be happening only on 64-bit machines. Is it happening with
the simple example too? Is it happening with gtk+/tests/print-editor too?

> Is it happening with the simple example too?
Yes. The preview does not work in the simple example either, because it tries
to print a PDF to show it with evince.
> Is it happening with gtk+/tests/print-editor too?
No. But evince fails to display the resulting pdf file. It shows just an empty
page and prints "Error: failed to load truetype font" to the terminal. But this
could also be a local problem.

------- Comment #26 from Armin Burgmeier 2006-08-03 10:45 UTC -------
Another problem, probably independant from the crashing PDF file creation, is
that examplewindow.cc binds the whole RefPtr to PrintOperation::signal_done()
instead of just a reference (or a pointer) to it. This causes the
PrintOperation to be never freed because the signal connection still holds a
reference to the PrintOperation.
As soon as the window (and thus the connection) is finally destroyed, memory
corruption seems to occur since the destroyed connection unrefs the
PrintOperation which itself wants to destroy the connection in the signal
destructor.

This sounds very suspicious. I suggest that you mention it on the cairo or gtk
mailing list.

Very clever. I'll figure out something to fix this if you don't first. But I
would prefer to avoid storing the connection and disconnecting them explicitly
because that complicates things.

Binding just a reference or a pointer to the RefPtr should do the trick.

I first tried to investigate this a bit further. It worked well when I took a
non-standard font (so, neither "Sans" nor "Monospace", but for example
"Rudelsberg" worked).
There seems to be a relation between this and the PDF crasher bug: When I use
the "Rudelsberg" font (or some other) in the simple printing example, it
produces a working PDF file instead of throwing that cairo exception. Can
others confirm this?

I can sort of confirm this. Here are my results:
"verdana 12": no crash, produced empty PDF
"Gentium 12": crash
"bitstream charter 12": no crash, produced good PDF

Between 2.6.4 and 2.6.14, an option was added to disable the default virtual
signal handlers (to save space for e.g. embedded applications). My guess is
that this is the problem you're seeing. Have you upgraded your glibmm version
as well?
