Angry SOAP denovo seg faults during map

Hi all,
I'm getting a seg fault while running map during a SOAP denovo run. I'm running on OSX with SOAPdenovo v 1.05.
I have checked to be sure input data has reads larger than 30 bp and that no empty lines exist. Does anyone have any other debugging ideas?

Here is my cfg:


Here's the map execution:

map -s soap.cfg -g test
K = 23
contig len cutoff: 25

there're 3424 contigs in file: test, max seq len 60625, min seq len 24, max name len 10
time spent on parse contigs file 0s
8 thread created
time spent on hash reads: 1s
4517379 nodes allocated, 5614229 kmer in reads, 5614229 kmer processed
time spent on De bruijn graph construction: 1s

time spent on mapping long reads: 0s

In file: soap.cfg, max seq len 70, max name len 256

I've been troubleshooting now by trying to divide and conquer. I've been halving the data set to see if i can get one to not seg fault. However, this strategy has really got me scratching my head. I can get the top 1st 1/4 and 2nd 1/4 to get past map. However, the top 1/2 fails. Also, when I concatenate the 1st and 2nd 1/4, it also fails (cmp shows this concat with the top 1/2 are identical).

Does anyone have ideas??
