Summary: using typedef-name error with typedef name hiding
struct name
Product: gcc
Version: 4.1.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: nathan.key...@oracle.com
G++ rejects the following code:
class Foo
{
bool a, b, c, d;
typedef struct Bar { } Bar;
virtual void foo(void) {
struct Bar bar;
}
};
example.cc: In member function ‘virtual void Foo::foo()’:
example.cc:6: error: using typedef-name ‘Foo::Bar’ after ‘struct’
example.cc:4: error: ‘Foo::Bar’ has a previous declaration here
example.cc:6: error: invalid type in declaration before ‘;’ token
but accepts many similar examples, including:
class Foo
{
bool a, b, c;
typedef struct Bar { } Bar;
virtual void foo(void) {
struct Bar bar;
}
};
This behaviour is reproducible on x86_64-redhat-linux (4.1.2 and 4.4.0) and
i386-pc-solaris2.11 (4.2.4, 4.3.4 and 4.5.1)
I'm uncertain if this is strictly legal or not per the standard, but it doesn't
seem to make sense to accept one of these cases but not the other.
