Octave-2.1.14 don't reclaim memory from globals variables that are cleared

[Joao Cardoso]

Hi,

It seems that the memory used by globals variables at initialization
can't be reclaimed when the variables are cleared (even with -x):

octave:1>        ; used memory: 9492K
octave:1> a=rand(1000);    17M
octave:2> clear a; a=rand(1000);    17M
octave:3> clear a; global b
octave:4> b=rand(1000); 17M
octave:5> clear b; b=rand(1000); 25M -- should be 17M
octave:6> clear b; b=rand(1000); 25M

repeat: (copy/paste)

a=rand(1000);
clear a; a=rand(1000);
clear a; global b
b=rand(1000);
clear b; b=rand(1000);
clear b; b=rand(1000);

I'm using octave-2.1.14 on sco-3.2v5.0.4

Joao
