Hmm.... the test worked OK for me! I'm really interested to figure out where 
the SIGABRT comes from: maybe some assert fires.

You mean the problems is only on those two toolsets? Yes, I think disabling 
signal handling in Boost.Test to see where the test fails would be very 
desired. BTW, you mention como, but I don't see that toolset in linux 
regression results.
