Super basic hash table set-up memory allocation errors - c++

Question

Yes I am still learning C++ and I am trying to create my own Hash.h header with several hash functions (non-cryptic) such as MurmurHash and CityHash. To start this off I just wanted a very basic implementation first. But it is not compiling as I have some memory errors. It is due to adding a entry where data is passed to the class function. Changing to pointers/references gave similar errors and I just can't seem to fix it. Can somebody see what is going wrong such that I know what to look for in the future? Thanks!
//Hash.h
template<class T>
class HashEntry{
private:
int key;
T data;
public:
HashEntry() {};
void putData(T input, int keyVal){
//SEGMENTATION FAULT HAPPENS HERE!!
key = keyVal;
data = input;
}
T getData(){
return data;
}
};
template<class T>
class Hash{
private:
int myFunc;
size_t sizeHash;
HashEntry<T> **table;
public:
Hash(int func, size_t size): myFunc(func), sizeHash(size-1) {
table = new HashEntry<T>*[sizeHash];
for (int i=0;i<sizeHash;i++) table[i] = NULL;
}
int hashFunc(int key){
try{
if (myFunc == 0){
return key % sizeHash;
} else if (myFunc == 1){
//other has func's
} else {string excep = "No such hash function!"; throw excep;}
} catch(string e) {cout << "Hash::hashFunc(): Exception Raised: " << e << endl; exit(0);}
return -1;
}
void addEntry(T data, int key){
int myHash = hashFunc(key);
table[myHash]->putData(data, key);
}
};
Call from main:
Hash<char> *myHash = new Hash<char>(0,10);
myHash->addEntry('s', 11);
return 0;
