Well, it also tells me that the exception is unhandled(!)... but the
thread survives:

First-chance exception at 0x7c812aeb (kernel32.dll) in XXX.exe:
Microsoft C++ exception:
boost::exception_detail::clone_impl<MyNamespace::error> at memory
location 0x0529a500..
Unhandled exception at 0x7c812aeb (kernel32.dll) in XXX.exe: Microsoft
C++ exception: boost::exception_detail::clone_impl<MyNamespace::error>
at memory location 0x0529a500..

The ~exception() is called several times (probably the exception
object is copied) at the closing "}" of:
throw_exception.hpp:
template<class E> inline void throw_exception( E const & e )

Then the execution proceeds to the breakpoint at the line after
BOOST_THROW_EXCEPTION
