Patch to make it compile on OS X (svn rev 30)

[GoogleCodeExporter]

Aras, I don't have an OSX/Intel system, so I've never compiled/run the code on 
it,
and to be honest most of the code in Debug.{h,cpp} has only been tested on my 
main
development platform.

In any case, it would be nice to fix that so that it works on OSX and other Unix
flavors too. Your patch seems to indicate that the sigcontext structure on 
darwin
does not contain the EIP pointer, but the code still uses it a few lines later. 
I'll
assume that you missed that and comment it out too. However, backtrace won't 
work
properly when called from a signal handler if the instruction pointer of the 
caller
is not set properly.

Here's a nice code snippet that shows how to do it in different Unix systems:

I've been looking how to do the same on OSX/Intel, but I haven't found 
anything. I'm
sure that somebody at OTEE knows how to do it. Could you find that out?

Thanks!

I've integrated your patch in revision 31, and added support for correct stack 
traces
in some other platforms. OSX is still not supported, thought. Please, change the
status to verified if it works for you.

It builds now. Didn't try whether it does the correct thing in case of a crash 
though. I can't find where I can mark 
the bug as "verified", so I'll just leave it as it is.

As for OS X exception handling code, for the editor we use ObjectiveC specific 
stuff (NSException etc.). I think I 
saw some more useable code in Mono to walk the stack on different platforms.

It's in the status box below the bug summary. It might only be available to 
project
managers. I finally found how to get the instruction pointer on OSX and added 
code
for that. It seems to work on PPC, so I hope it does work on x86 too. I'm 
closing
this now.
