bittyrant cant run on 7 release but ok on 7 stable

[Tsu-Fan Cheng]

Hi,
    just  upgraded to 7.0-release a few days ago, but found bittyrant
error when evoked:
# An unexpected error has been detected by HotSpot Virtual Machine:
#
#  SIGSEGV (0xb) at pc=0x2810c887, pid=58098, tid=0x28201100
#
# Java VM: Java HotSpot(TM) Client VM
(1.5.0_14-p8-tfcheng_16_apr_2008_20_53 mixed mode)
# Problematic frame:
# C  [libc.so.7+0x61887]  calloc+0x9d7

I then recompiled jdk1.5, swt and bittyrant. still can't run. any
idea?? appreciated!!
