------- Comment #3 from paolo dot carlini at oracle dot com 2009-09-01 20:06 ------- As a matter of fact, this snippet doesn't link:
struct Inner { Inner() : data(0) {} template<class IStream> explicit Inner(IStream&); int data; }; int f() { Inner inner1; Inner inner2(inner1); } Now, as a matter of fact, the fact that the above code doesn't link means that Inner isn't CopyConstructible (First line of Table 30 in C++03), thus, it is invalid to instantiate std::vector with it, as you are doing in Outter. I'm adding Jason in CC just in case he has something to say about the C++ proper issue. -- paolo dot carlini at oracle dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu dot org Status|UNCONFIRMED |RESOLVED Component|libstdc++ |c++ Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41216
