windows - Imagemagick -subimage-search command hanging -

- 

compare.exe -metric rmse -subimage-search screenshot.png locator.png null

this command hangs , runs cpu @ 13% until press ctrl + c

other compare commands working fine!

the option '-subimage-search' searches second image @ every possible location in first image. slow! very slow.. when have large images can take lot of minutes complete. option '-debug all' can see happening make process slower.
