Subject: Re: New: ICE caused by default template argument
FWIW, on gcc 4.3.2, I get the error:
test.cc: In function 'void breakMe()':
test.cc:17: error: a cast to a type other than an integral or
enumeration type cannot appear in a constant-expression
test.cc:17: error: template argument 2 is invalid
test.cc:17: error: invalid type in declaration before ';' token
The source listing annotated with line numbers is:
1 #include <string>
2 #include <typeinfo>
3
4 template<class FILTER, const std::string& filterName =
std::string("") >
5 class Filter
6 {
7 public:
8 virtual const std::string& getFilterName() const
9 {
10 static const std::string name = filterName;
11 return name;
12 }
13 };

15 void breakMe()
16 {
17 Filter<int> boo;
