>Description:
A legal instantiation of a multi-argument constructor 
template fails with a compilation error if the first 
argument is a temporary object created using a default 
constructor.

This problem prevents a common use of the std::locale class:

std::locale loc(std::locale(), new Myfacet);

This statement produces the following error messages:

"type specifier omitted for parameter"
"parse error before 'new'"
  
>How-To-Repeat:
Compile the code in the file attachment:

gcc template_bug.cpp
>Fix:
Unknown.  The error appears to be in the C++ parser.
