#1440 closed defect

Problem with shapefile indexes and 64bits long integers. — at Initial Version

Description 

After upgrading to FreeBSD/AMD64, polygons started to randomly appear and
disappear on maps created by mapscript (or mapserver itself) from shapefiles. 

The problem seems to be with searchDiskTreeNode in maptree.c.:

  long offset;
  [..]
  res = fread( &offset, 4, 1, disktree->fp );

A long is 8 bytes on FreeBSD/AMD64 (and probably many other 64bits) plaforms. 
Initializing offset to 0 solved the problem here. 

readTreeNode is probably also affected.
