Just in case nobody noticed, seems like Boost.Test is failing with Intel 8.1. This error appears at run-time in plenty of tests: Exception in "call_test_main": memory access violation C:/boost_regression/boost/libs/test/src/unit_test_suite.cpp(127): fatal error in "call_test_main": Test case initialization has failed *** errors detected in test case "call_test_main"; see standard output for details Test case "call_test_main" was aborted due to uncaught exception, user assert or system error EXIT STATUS: 200 I'm quite sure the problem is in Boost.Test, since the crash happens at several different libraries, all of which use this Boost.Test. Maybe someone with local access to this compiler can debug some of the failing tests and narrow down the locus of the problem. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
