[Walter Roberson]

Too vague. We have no idea what is in mserConnComp or what the rest of line 66 is.

My most immediate speculation would be that mserConnComp might have ended up being all 0.

If you'll use eg. single datatype for pixel indexes, than you'll get numerical errors similar to the one you've presented when performing the conversion ind2sub.

Minimal working example:

image of size [5860, 5091] we have the following problem: 16779030 (single) is converted to [1849, 2.864000244140625e+03] (double)
