Problem with Boost and GCC 4.1

[nobody]

There is a problem when using slots & trackable with GCC 4.1 - I don't know whether this is a GCC problem or a Boost problem, but it affects us (OpenWengo) on both Fedora Core and Feisty, since both distribute gcc 4.1.

I'm attaching a test case - the expected output is:

create A
fire SGN
A
create B
fire SGN
A
B
delete A
fire SGN
B
delete B
fire SGN
exit

This doesn't happen :)
