I get this in vs7.1 with sp1: ------ Build started: Project: multi_index1, Configuration: Debug Win32 ------ Compiling... hash_test.cpp f:\boost_1_34_0\boost\mpl\aux_\preprocessed\plain\apply_wrap.hpp(48) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'f:\vs70builds\6030\vc\Compiler\CxxFE\sl\P1\C\main.c', line 1164) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Build log was saved at "file://g:\cpp\boost\multi_index1\Debug\BuildLog.htm" multi_index1 - 1 error(s), 0 warning(s) yet this can compile well in gcc 3.4. i really don't know why. many thanks for JOAQUIN LOPEZ MU?Z 's past help.;-) 百 万 玩 家 同 玩 的 乐 园，人 气 爆 发 的 梦 幻 西 游
