Fails on ICC 10.0.25 on Windows 32bit with:
\test.cpp(6): error: more than one instance of overloaded function
"std::copy" matches the argument list:
function template "_OutElem *__cdecl std::copy(_InIt, _InIt, _OutElem
(&)[_Size])"
function template "std::_Enable_if<<expression>, _OutIt>::_Result __cdecl
std::copy(_InIt, _InIt, _OutIt)"
argument types are: (char [10], char *, char [10])
std::copy( a, a + 10, b );
[Compiles OK as a MSVC 2005 project but fails as above when converted to an
Intel project]
I certainly care because ICC generates the best vectorised code in many of
our apps. Use it mainly with Linux 64 bit and *very* occasionally Windows 32
bit.
Last time I tried to help out with regression testing (admittedly ad-hoc as
I can't dedicate a resource) it wasn't really seen as necessary since there
was already reasonable ICC coverage. Has this changed?
