#291: GMM Estimate bug

---------------------------+------------------------------------------------
 Calling GMMs object Estimate method fails with "double free or corruption"
 in some cases. Simple code demonstrating this behaviour in enclosure. The
 conditions to cause this faulty behaviour are: number of columns is odd
 and higher than some threshold (e.g. 23 fails, 3 is OK) and some columns
 have same values.

 Tested with mlpack 1.0.5 and 1.0.6, libarmadillo.so.3.900.0 and
 libarmadillo.so.3.2.3 (on wheezy).
