^^^^^^^^^^^^^^^^^^^
Here you have defined a char pointer, which is, at this point, pointing
nowhere, to utter garbage.

^^^^^^^^^^^^
Here you are trying to send a string, located at what 'map' points
to, to the player. Where in your code, did you actually allocate some
memory for map to pint to, a buffer that is? And where did you read in
your map file and actually store soemthing there?
If you did neither, then this is why you crash. Page_string expects to
find a null terminated string at the location pointed to be the map variable.
