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
