Re: [boost] [Boost-users] [ScopeExit/Typeof] Can't build simple test in debugmode (MSVC 7.1 and 8.0)

Hi,

I've moved this to the dev list, because it should probably be mentioned in
the documentation somewhere. I'm not sure whether it belongs in Typeof or
ScopeExit.

I've tried building the hello.cpp example that comes with ScopeExit with the
same results (as in my original message). I think I have narrowed down the
cause. Building fails whenever "Program Database for Edit & Continue (/ZI)"
is set in the project properties. Changing this to "Program Database (/Zi)"
or any other fixes the problem. Is this a compiler bug?

I never use Edit & Continue anyway, but I thought it might be helpful to
others to mention this problem somewhere.

Best regards,
Christian Larsen
