Integer divide by zero is treated as non-fatal system error 
(if it's actually produced by your hardware/compiler). It should not 
lead to the test being aborted.

All kinds of memory access violations are treated as fatal system error. 
This will abort the test execution (well it will try to do it gracefully,
though some other things might fail in process)

Return control where?

Once any of the above are triggered, the test case is definitely aborted.
whether or not test will continue depend on type of error.

You can tell Boost.Test not to catch system errors/signals using command line
argument "--catch=false" or "-s false"
