[boost] Repost: [signals] expected failure markup for como

Seems like this question was missed... Doug, as you wrote the note I'm referring to below, do you have anything that could shed some light on it? TIA, Markus Markus Schöpflin wrote:

There are currently two test failures (dead_slot_test, and trackable_test) which are marked as expected for como. The note says: 'The failure is caused by a compiler bug, which has been reported to the compiler supplier (or is already known to them).'

Does anyone know the exact circumstances of this compiler bug or even has a small reproducer? Tru64/CXX has the same failures and I would like to submit a bug report to the vendor.
