Re: segfault on solaris10/sparc

[Fred Kiefer]

If you look at the code in NSData.m you will see that just before the failing 
line there is an #if NEED_WORD_ALIGNMENT clause. The question now is why this 
isn't defined in your case. You will have to report back the configure results 
of your Sparc machine.

Hope this helps,
Fred

On the road
