[Bug c++/19503] New: Parsing problem in the constructor call of temporary object

[timo dot erkkila at tut dot fi]

Hello,

the following code

 struct A { };
 struct B { B( A& ) { } };

 void foo( A& a ) { B( a ); }

results in this output:
 g++ t.cc -c

 t.cc: In function `void foo(A&)':
 t.cc:4: error: declaration of 'B a' shadows a parameter
 t.cc:4: error: no matching function for call to `B::B()'
 t.cc:2: note: candidates are: B::B(const B&)
 t.cc:2: note:                 B::B(A&)

With a workaround (extra cast) in foo, it however compiles ok:

 void foo( A& a ) { B( (A&)a ); }

Yours,

Timo Erkkilä

Ps. g++ -v
