[antlr-interest] C++ Map not usable, always SEGFAULT

[Christian Benjamin Ries]

  Hello, I'm a little bit frustated.

I'm trying to use a C++ Map with ANTLR, but I get a segfault always.

The source is pasted below, any suggestions?

The output is always:
--
cr at ....:~/dsl/output$ ./dsl ../install1.host_dsl
NetIP: 127.0.0.1
hlist size: 0
Segmentation fault

1. Snippet - class Host with Map:
---- 1. START
class Host {
private:
   Network network;
   Distribution distribution;
public:
   Host();
   Host(const Host& host);
   ~Host();
   void setNetwork(Network network) { this->network = network; }
   Network & getNetwork() { return this->network; }
   void setDistribution(Distribution distri) { this->distribution = distri; }
   Distribution & getDistribution() { return this->distribution; }
};
struct HostMapCompare {
   bool operator()( const char* s1, const char* s2 ) const {
     return strcmp( s1, s2 ) < 0;
   }
};
typedef std::map<const char*, Host, HostMapCompare> HostList;
