--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
(In reply to Jonathan Wakely from comment #5)
> Reduced thanks to K-ballo:
Hmm, clang compiles and gives:
member
While both GCC and ICC compiles and gives:
non-member
And MSVC rejects it with:
<source>(15): error C2593: 'operator <<' is ambiguous
<source>(10): note: could be 'void my_stream::operator <<<const
char(&)[12]>(T)'
with
[
T=const char (&)[12]
]
<source>(6): note: or 'void operator <<<my_stream,char[12]>(C &&,const T
(&))'
with
[
C=my_stream,
T=char [12]
]
<source>(15): note: while trying to match the argument list '(my_stream, const
char [12])'
This might be the first time I have seen all four compiler full on disagree for
a testcase like this (with GCC and ICC agreeing).
