I recommend using tmxlite or if you must sfml-tmxloader.

Secondly you should learn some modern C++ where never use owning raw pointers and instead make use of unique (and shared) pointers and thus pretty much do away with manual memory management.

As for the crash:

image = tilesetElement->FirstChildElement("image");
std::string imagepath = image->Attribute("source");

It's most likely that FirstChildElement("image") returned nullptr and then you try to access it, causing an access violation, thus crash.
