Creating a lambda at global scope will result in a compile error if the lambda includes a for loop.

Details (expand)

Visual Studio 2010 SP1

Define the following lambda at global scope.
auto global_lambda = []{
    for(int i = 0; i < 100; i++)
    {
    }
};

Windows 7

Compilations results in the following errors:
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2143: syntax error : missing ')' before ';'
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2143: syntax error : missing ';' before ')'
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2143: syntax error : missing ';' before ')'
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2065: 'i' : undeclared identifier
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2065: 'i' : undeclared identifier
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(7): error C2059: syntax error : ')'
1>w:\documents\visual studio 2010\projects\compilerbug\compilerbug.cpp(8): error C2143: syntax error : missing ';' before '{'

The lambda should compile without error.
