>Environment:
Cygwin (latest), linux redhat 7.3, SGI Irix 6.5.13
>Description:
struct Test
{
template <typename T>
void test(T*) {}
};
template <typename ObjType>
struct Foo
{
Test _state;
int _i;
void reset()
{
_state.test(&_i); // ok
_state.test<ObjType>(&_i); // parse error here if...
}
// ... and only if following is not
// same name as Test::test!!!!
template <typename TT>
void test2() {}
};
int main()
{
Foo<int> test;
test.reset();
}
>How-To-Repeat:
Just try to compile the file with "g++ -c file.cc"
>Fix:
none except hack: add extra parameters to function so it can deduce template parameter
Colleague has reported that these may work too (not tested rigorously):
_state.template test<ObjType>(&_i); //avoids the error
_state.Test::test<ObjType>(&_i); //avoids the error
