I am trying to make a general StoreIniFile function that will take a VectorMap<String, String> and save it's contents as a INI formatted string.

This is what I have so far, which fails on the call to cfg.Get() with a failed assert like "i > 0 && i < size"...

int StoreIniFile(VectorMap<String, String> cfg, const char *filename) {
	int i = 0;
	String cfgstring;
	Vector<String> keys = cfg.GetKeys();

This would "pick" cfg, effectively destrying its content. (Same applies to the function parameter cfg!) You can use

[code]
const Vector<String>& keys = cfg.GetKeys();
[/quote]

if you need to "see" keys as Vector, anyway, I believe you really do not:

int StoreIniFile(const VectorMap<String, String>& cfg, const char *filename) {
	int i = 0;
	String cfgstring;
	if(cfg.GetCount() > 0) {
		PromptOK(Format("found %i items", cfg.GetCount()));
		for(i = 0; i < cfg.GetCount(); i++)
		{
			PromptOK(Format("Key %i: %s Value: %s", i, cfg.GetKey(i), cfg[i]));
			cfgstring << cfg.GetKey(i) << "=" << cfg[i] << "\n";
		}
	}
	//SaveFile(filename, cfgstring);
	return true;
}

Also notice the change in function signature...

I seem to have some gaps in my C++ knowledge,

Actually, you need U++ knowledge here, this is not quite a traditional way of C++.
