Andrew,

(I am sorry if this is just a rehash of the past, but it's new to me :-)

The problem of backtracing past main.  It shows up when debugging a 64-bit 
application.  it does NOT show up when debugging a 32-bit application.  Both 
on powerpc64--linux.

So when testing annotations, it will be a known failure on powerpc64--linux, 
when debugging a 64-bit application, because backtrace went past main.

I agree it is a known failure.  But it has nothing to do with annotations.  
Annotations work fine.  

I can see what a mess we would have if each test started trying to defend its 
self against bugs outside of the area being tested.

It it well known that a 'KFAIL' durring a test may have nothing to do with 
what is being tested? 

Is there an equivelent failure for 'I just can't run this part of the test?'

OK, so I wrote a test for the 'backtracing past main' problem.  Here it is 
along with a couple of logs:
