I simplified the script to make it easier to set up here, and since 
you're using v2.8 I removed the portion for earlier versions:


on mouseUp
   local tNum
   local twID
   local tFol
   local tDest

   put 500 into tNum
   put the windowID of this stack into twID
   put "/Users/rg/Desktop/untitled folder/" into tFol
   set the defaultfolder to tFol

   repeat with x = 1 to tNum
     if the mouse is down then
       exit to top
     end if
     put x & ".png" into tDest
     put x into fld "counter"
     export snapshot from grp 1 to file tDest as PNG
   end repeat
   answer "Done!"
end mouseUp

Running this script twice in both MC and Rev completed without error, 
and afterwards the memory allocation for each was roughly the same as 
before.

What suggests this crash is specifically a memory leak?
