[boost] Intel 8.1 and Unit test suite?

All the tests that use the Unit Test Suite fail with the Intel 8.1 Beta compiler, has anyone seen and/or reported this to Intel already, or have any ideas what's going on? Typical errors are: Exception in "test_conversion_to_char": memory access violation c:/data/boost/develop/boost/libs/test/src/unit_test_suite.cpp(127): fatal error in "test_conversion_to_char": Test case initialization has failed The access violation appears to be a vtable lookup problem, but I'd like to be sure it's not a boost problem before reporting it. Thanks, John.
