-K in 6.12.2

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, ----------------- Serge Mechveliani mechvel@botik.ru
