Bug ID: 18104
Summary: The name of a function doesn't decays to a function
pointer automatically
Product: clang
Version: 3.3
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: release blocker
Priority: P
Component: C++11
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Based on the C++ Programming Language 4th Edition (C++11), the following
example compiles with GNUC++4.9 but needs a function pointer in front of the
function name when using CLANG.
#include <future>
void f()
{
}
int main()
{
packaged_task<void()> pt {&f}; //use '&' to compile
}
I get this error when the ampersand is removed:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/memory:1670:45:
error: multiple overloads of 'address' instantiate to the same signature
'const_pointer (const_reference) const noexcept'
_LIBCPP_INLINE_VISIBILITY const_pointer address(const_reference __x) const
_NOEXCEPT
