Hi gurus,

VC++7.1/8 complains:

error C2355: 'this' : can only be referenced inside non-static member

about:

struct xxx : std::vector<int> { void test() { BOOST_FOREACH(int x, *this) { } } };

GCC compiles. Is this maybe a bug of VC++?

Looks like it. I can't think of a work-around. :-(

I just wanted to know whether it is legal or a bug. That is somewhat problematic if 'xxx' doesn't know the base range type. I note user workaround: struct xxx : std::vector<int> { void test() { foreach(*this); } template< class SelfT > void foreach(SelfT& self) { BOOST_FOREACH (int x, self) { } } }; Thanks! -- Shunsuke Sogame

A much simpler workaround that compiles under VC7.1 is:

struct xxx : std::vector<int> { void test() { xxx* This = this;

BOOST_FOREACH(int x, *This) { } } };

Doh! A mysterious reason prevented me from writing even self type... Bug makes bug. :-) Thanks again! -- Shunsuke Sogame

What happens if you define test() out of line? Do you still get the error? Joe Gottman
