Another one:

$ eshost -x 'var replaceTracker; function replaceFunc(key, value) { replaceTracker += key + "("+(typeof key)+")" + JSON.stringify(value) + ";"; return value; } replaceTracker = ""; JSON.stringify([1,2,3,,,,4,5,6], replaceFunc); print(replaceTracker);'

Thank you much for the report. I committed a fix which should be published next week. Meanwhile xst 8.6.2 is available so you can test with eshost.

The fix is now committed.
