Memory allocation error in Generalized Least Squares ramp fitting. #4683

While working on JP-1156 ("Compare GLS and OLS algorithms in ramp fitting"), I have discovered that the Generalized Least Squares (GLS) algorithm of ramp fitting crashes with large datasets, e.g. 2k x 2k x 200 reads.

Has this been resolved?
