Matlab program that runs fine in Windows gives multiple errors in Linux.

Both versions are 2012b. The program is:

The lines highlighted with asterisks are the ones that cause it to freak out on Linux.

midpointL(currentTrial, :) = length(xxl(:, 1));

The above causes a fatal Segmentation Violation that forces Matlab to close. The same happens with the code that saves the data as STMEMD.mat

elseif currentElectrode == 3.....

The above code gives an error saying there's a subscripted dimension mismatch in the "parallel" function itself when called by "parfor currentTrial = 1:12". What's weird is that it works fine with the first two if statements preceeding it. There is literally no difference between the results of "currentElectrode == 3" and "currentElectrode == 2". Matrix dimensions are identical. In fact the error doesn't display until the program tries to exit the parfor loop.

Occasionally get inconsistent Segmentation Violation crashes on other lines but it's intermittent.
