The following used to compile in gcc 3.3:
$ cat foo.cc
typedef void (*Function)(int n = 1);
$ g++ -c foo.cc
$
It doesn't compile anymore in gcc 3.4:
$ cat foo.cc
typedef void (*Function)(int n = 1);
$ g++ -c foo.cc
foo.cc:1: error:
default arguments are only permitted for function parameters
$
Although I'm not sure this is legal C++, I've opened a bug report because the
following does work with gcc 3.4, which seems inconsistent:
$ cat foo.cc
struct MyClass {
typedef void (MyClass::*Function)(int n = 1);
};
$ g++ -c foo.cc
$

For the first example: Search converges between 2002-12-14-trunk (#159) and 2002-12-29-trunk (#160). This would be when the new C++ parser came in. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17634 ^ permalink raw reply [flat|nested] 4+ messages in thread
