Subject: possible memory leak in 1.6 (PR#2160)

Hi,

I noticed the following problem with 1.6.0 (which was not present in 1.5.1): 

I work with very large datasets and encountered a problem with memory
allocation,
(probably a memory leak).  I wrote a programm with a loop.  In this loop in
each
iteration I create a  very large matrix and assign it to a variable which
is the SAME for all the iterations.  So at each round the new matrix overwrites
the old  matrix.  In 1.5.1  the garbage collector seems to clean up the old
unused memory.  Unfortunately, in 1.6.0 with each round the memory used by R
increases until the R process is killed. 

Is there any way around this?

Many thanks and best regards,

  A.L. Boulesteix
