http://www.cplusplus.com/reference/ios/ios/operator_bool/ So in C++11, there should be an implicit conversion to bool *if* the conversion gets forced by the return type. (if you use "auto" then operator= just tries to copy the stream which IIRC isn't allowed) In C++03 the conversion is to void*, but I suppose the compiler is figuring out that it can do a chain of conversions by then going from void* to bool? I forger under what circumstances that's allowed. The version as-is should be working in C++11, I believe. I wouldn't swear that this was a compiler bug, though: you're mixing clang with libstdc++, right? This could be another one of those "libstdc++ tries to detect internal gcc preprocessor tokens and gets confused by clang" bugs. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-devel mailing list Libmesh-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-devel
