The following snippet refuses to compile with the gcc-3.4 branch (and with the 
trunk, I guess). It compiles fine with previous versions. The offending line 
and work-arounds are indicated as comments. Is it the parser, or is it me? 
 
#include <string> 
 
int main() 
{ 
  using std::string; 
 
  string s1(string( (string     )("")));   // OK 
  string s2(string( (const char*)("")));   // Does not compile 
  typedef const char* charp; 
  string s3(string( (charp)("")));         // Workaround: intermediate typedef 
  string s4((string( (const char*)("")))); // Workaround: extra parenthesis 
  return 0; 
}
