CodeGear 6.10.0 has a bug, which causes an internal compiler error when you try to specialize std::swap. As was reported by Christopher Greene <http://qc.codegear.com/wc/qcmain.aspx?d=68959> and me <http://qc.codegear.com/wc/qcmain.aspx?d=69196>. To my surprise, the compiler error appears to have gone away automatically, and three boost/utility/swap tests now have an "unexpected success": www.boost.org/development/tests/trunk/developer/utility-swap_.html www.boost.org/development/tests/trunk/output/siliconman-boost-bin-v2-libs-utility-swap-test-specialized_in_std-test-borland-6-10-0-debug.html Is there any explanation to this unexpected success? The compiler version hasn't changed, apparently... Kind regards, -- Niels Dekker http://www.xs4all.nl/~nd/dekkerware Scientific programmer at LKEB, Leiden University Medical Center
