Hi!
Current -ftemplate-depth default is IMHO way too low, e.g. kdevelop hits is
without problem when using lots of << operators (simplified testcase like:
template <class T>
class foo
{
public:
foo<T>& operator <<(const T&x) { return *this; }
};
int main(int argc, char **argv)
{
foo <char *> baz;
baz << "1" << "2" << "3" << "4" << "5" << "6" << "7" << "8" << "9" << "0"
<< "1" << "2" << "3" << "4" << "5" << "6" << "7" << "8" << "9" << "0"
<< "1" << "2" << "3" << "4" << "5" << "6" << "7" << "8" << "9" << "0"
<< "1" << "2" << "3" << "4" << "5" << "6" << "7" << "8" << "9" << "0"
<< "1" << "2" << "3" << "4" << "5" << "6" << "7" << "8" << "9" << "0"
<< "1";
}
). The comment above the default sais it is just an arbitrary value, is
there some reason to keep it that low?
