[Bug c++/29252] Strange "No matching function for call" compilation error with G++ 4.1

I think the error message is perfectly clear: it says that there is no
function
   foo (X)
but that there is a function that provides
   foo (X&)

We've gone through this many times that there is no way to say "see, you
try to bind an rvalue to a reference, this isn't working" because the
overload set of candidates may be larger than the single function above
and there is no way to guess what the user may mean.

So closing...

W.

The error message is broken but this is invalid code as you cannot bind a
temporary to a reference argument.

Hi,

For your convinence, the following is the reproduction code.

Many Thanks,
-Kelvin


Compilation error
=
no matching function for call to tdat_hash_map
>::func(MemAllocator)

main.cpp:6: note: candidates are: static void
tdat_hash_map<_AllocType>::func(_AllocType&) 
[with _AllocType = MemAllocator]


Repro code
===
template  class MemAllocator{};

template  class tdat_hash_map {
public:
typedef _AllocType _Alloc;
static void func(_Alloc&) {};
};

int main()
{
typedef tdat_hash_map > Map;
Map::func((MemAllocator) (MemAllocator()));

return 0;
}

You didn't show us the code that generated the problem. We can't do anything
without that. Please read

for more information.

Best
  W.
