Hello, I get this internal compiler error below when compiling boost-regex (from cvs today 11 nov 2003) using STLport-4.6. The error do not show up when using STLport-4.5.3 though. Any ideas? Problem in STLport-4.6 or boost, that's the question? cl -Ic:\EON\builds\head\Development\ExternalLibraries\include\stlport /nologo /MT /W3 /GX /O2 /GB /GF /Gy /Ic:\EON\builds\head\Development\ExternalLibraries\include\stlport /I..\..\..\ /D_MT /DWIN32 /DNDEBUG /D_MBCS /D_LIB /c -DBOOST_REGEX_STATIC_LINK -D_STLP_USE_STATIC_LIB -D_RTLDLL -Y- -Fo./vc6-stlport/libboost_regex-vc6-mt-sp-1_31/ -Fdvc6-stlport/libboost_regex-vc6-mt-sp-1_31.pdb ../src/c_regex_traits.cpp Command line warning D4002 : ignoring unknown option '-Y-' c_regex_traits.cpp ..\..\..\boost/detail/allocator.hpp(67) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information NMAKE : fatal error U1077: 'cl' : return code '0x2' Stop.
