Is it a bug in libc++ where it's doing the wrong thing inlining some values for basic_ios (my guess is based on the snippet example at: http://www.cplusplus.com/reference/iostream/ios/clear/ ): $ p4 diff -du ios --- //depot/user/gcooper/atf-head/src/contrib/libc++/include/ios 2012-05-20 04:37:04.000000000 0000 +++ /scratch/p4/user/gcooper/atf-head/src/contrib/libc++/include/ios 2012-05-20 04:37:04.000000000 0000 @@ -575,10 +575,10 @@ _LIBCPP_ALWAYS_INLINE _LIBCPP_EXPLICIT operator bool() const {return !fail();} - _LIBCPP_ALWAYS_INLINE bool operator!() const {return fail();} - _LIBCPP_ALWAYS_INLINE iostate rdstate() const {return ios_base::rdstate();} - _LIBCPP_ALWAYS_INLINE void clear(iostate __state = goodbit) {ios_base::clear(__state);} - _LIBCPP_ALWAYS_INLINE void setstate(iostate __state) {ios_base::setstate(__state);} + _LIBCPP_INLINE_VISIBILITY bool operator!() const {return fail();} + _LIBCPP_INLINE_VISIBILITY iostate rdstate() const {return ios_base::rdstate();} + void clear(iostate __state = goodbit) {ios_base::clear(__state);} + _LIBCPP_INLINE_VISIBILITY void setstate(iostate __state) {ios_base::setstate(__state);} _LIBCPP_ALWAYS_INLINE bool good() const {return ios_base::good();} _LIBCPP_ALWAYS_INLINE bool eof() const {return ios_base::eof();} _LIBCPP_ALWAYS_INLINE bool fail() const {return ios_base::fail();} I'm building clang and libc++ in my VM to confirm.
