Initial Comment: trying out the new boost_1_31_0 and i'm having problems using the updated regex library as a precompiled header. ...\boost\regex\v4\perl_matcher_common.hpp(660) : 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 I'd be curious if the .Net compiler had the same problem, but I assume it doesn't. I can say that if I pull the regex.hpp out of stdafx.h and put it into each .h or .cpp file that references boost::regex, I get a clean compile. However, I have dozens of tiny projects that would require this change.
I've tried all sorts of things to try and fix this, but I can't see any solution. As you rightly say Visual Studio .NET and .NET 2003 don't have this issue (I've checked). The strange thing is, the pre-compiled header builds OK, it's only when you come to use it that the error occurs. If anyone has any ideas I'd appreciate it. John
