This test:
http://www.meta-comm.com/engineering/boost-regression/developer/output/Martin%20Wille-bin-boost-libs-signals-test-signal_n_test-test-gcc-3-4-1-linux-debug.html
(TinyUrl: http://tinyurl.com/6xdfa )

shows that if libstdc++'s debug mode is used then the test fails because
the debug mode catches an invalid use of a singular iterator.
This is probably what is causing the fails in the other toolsets, except
that the debug mode doesn't intercept the error and so it results in a
crash.
