cairo crash on NetBSD/sparc

[Riccardo Mottola]

Hi all,

I updated my Sparc/NetBSD box. Up to a couple of weeks ago, I was 
running an ancient NetBSD 2.x, ancient gcc and ancient cairo setup.

Now I have current NetBSD 6, gcc 4.5.3 and cairo cairo-1.12.16

I compiled core, compiled Ink, I start gdnc and gpbs before (slow 
machine, networked display)

Ink starts, I can type a couple of words, then I get a crash reported below.

I wonder if it us or cairo? Perhaps we are calling something badly? The 
stack trace seems to go on and on.
Sadly in #9 the glyphs are "optimized out"
in #10, if I try, I get:

(gdb) p glyphs
$1 = (const NSGlyph *) 0xefffda18
(gdb) po glyphs

Program received signal SIGBUS, Bus error.
0x20abc294 in objc_msg_lookup () from /usr/lib/libobjc.so.3
