Hi gurus,

Under VC7.1/8,

struct xxx : std::vector<int> { virtual void foo() = 0; };

void test(xxx& rng) { BOOST_FOREACH (int x, rng) { } }

makes error,

foreach.hpp(361) : error C2259: 'xxx' : cannot instantiate abstract class

GCC3.4.4 compiles. Is this wrong code?

Thanks for the bug report. This is now fixed both in CVS HEAD and in the release branch.

Thanks for fast response! cvs seems to be outage, but that error reminded me of "Prefer composition to inheritance" to change my codes :-) -- Shunsuke Sogame
