-K in 6.12.2

[Serge D. Mechveliani]

Dear GHC developers,

I am trying  ghc-6.12.2  on  Debian Linux, i386-family,
on the  DoCon test.
There is a difference in memory management, with respect to 6.12.1.
For the test compiled under -O,  2300k  in  "./Main +RTS -K2300k -RTS"
is the minimal memory option of this kind for the test to finish without 
break.
In  6.12.2,  90k  is sufficient, maybe, GHC ignores this "-K", -"M" ...
Could you explain, please?

Regards,
