Cairo Crash when Displaying Remotely to Solaris 8

["Richard Boaz" <riboaz xs4all nl>]

Hi,

My program is crashing with the traceback provided below when executed
under the following scenario:

1) user is logged into a RedHat Enterprise Linux 4 machine via ssh -X
2) user executes the program for display back onto his machine
3) user machine = Sun Sparc architecture, running Solaris 8

This same scenario, executing remotely while displaying locally, works
without issue when the display machine is either another Linux machine or
a Mac OS X machine (either platform).

The program is crashing at startup (in call to gtk_widget_show_all()), and
as can be seen from the traceback, is failing in its calls to cairo.

I conclude that there is some issue related to the combination of calls to
cairo and the Solaris 8 machine, though this confuses me a bit.  Is it not
so that when executing and displaying on different machines, all calls to
graphics libraries not XLib occur on the executing machine, while all
calls to XLib itself occur on the displaying machine?  If this is true,
then why would calls to cairo fail only when displaying back to a Solaris
8 box?

On the other hand, that said, perhaps my assumptions are wrong and I'm
missing something fundamental here.

Anyone understand this and/or able to identify where this scenario is
going wrong and why?  And, the obvious follow-up, what is required to get
this to work as it should?

thanks in advance for any pointers,

richard
