Re: cairo crash on NetBSD/sparc

[Fred Kiefer]

NSGlsph is not a class, it is just a simple typedef, you should try to output 
the values with

p *glyphs

It would also help to include the actual error message, in you case the 
segmentation fault, in the debug output.
Most likely it is us who are causing the problem. On the other hand, cairo 1.12 
is really old, could you please try to use a more recent version? This will 
require to recompile GNUstep back, as we have to check for the cairo version 
there.

Hope this helps,
Fred

On the road
