Default Segmentation fault (core dumped) at contig step during SOAP denovo assembly

Hi all,
I intend to assembly a 2.5G-sized genome with 2.4 G shut gun reads (100 bp) and 2.9 G mate-paried reads (75 bp). I run the SOAP denovo (v 1.05) step by step. The first step, pregraph, succeed in running. However, at the second step, the contig step, SOAP denovo reported the error message. The command line and error message are shown as below:

SOAPdenovo-31mer pregraph -s shutgun_Q.gPET_Q.SOAP.kmer_21.config_1 -K 21 -a 650 -p 40 -R -o shutgun_Q.gPET_Q.K21

SOAPdenovo-31mer contig -g shutgun_Q.gPET_Q.K21 -R
Version 1.05: released on July 29th, 2010

there're 415826527 kmers in vertex file
there're 1447198408 edge in edge file

I am eagerly looking forward for your help.
