Strange things happening when I try to use an array...

Strange issues when running this code...I have not worked with my Arduino in a while (since before v1.0 of the IDE) so I am not sure what all has changed...As it states in the comments of the code, any time I try to read from this array, serial output does not happen (which was put in to try and debug things) and I get nothing but static on my OLED screen...
Any ideas? I am hoping my eyes are just too tired from manually entering this QR pixel by pixel to see the obvious...

Troubleshooting so far:

Note 1: This also happens when I try to read data from the array outside the for-loop even using fixed values, such as trying something simple like "if(qrData[5][5]==0)" or "Serial.println(int(qrData[5][5]));" As well as if I try to manually set an element, such as " qrData[5][5]=true;"

Note 2: And to clarify, when the other IF-THEN is used, I do mean ALL serial output fails, including the line that should be printed during setup well before attempting to access the array...This kind of makes me wonder if the error is in the compiler rather than the code, since it supposedly compiles properly.

Note 3: If I try to manually set an element the same thing happens as in Note 1...IE:

If the SD lib creates its buffer even when not used, then you are using a minimum of 1353 bytes with just the SD and array. If you use an Uno you may have swallowed all the RAM with the oled lib and such.

Wow....How did I not notice that was still in there...That was definitely the cause, worked like a charm after that...I think I am going to try to shrink my memory usage down a bit more by storing these pixels as bits rather than full bytes as well...Thanks!

Here is a link to my BitBool class, it will handle storing/reading the bits as well as work just like a normal array: BitBool Class ( boolean array ), upto 16000 elements on UNO. - Libraries - Arduino Forum
