It's fixed in the latest beta 

It was doing the right thing but not enough. For each line of the output it executes the regex expressions. If they return a valid integer in column 2 it is accumulated into textSize, dataSize or eeepromSize.

The problem was that Visual Micro was not accumulating, so the last value of each group was used. 

Example

We needed textSize += size instead of textSize = size 

Now the values are identical to the Arduino Ide and will be interesting to see what it shows for your sketch when debug is active. It should warn and not attempt to upload.
