SOAPdenovo: free(): invalid pointer:

I struggled with SOAPdenovo for 3 hours today. It was crashing at pregraph, shortly after parsing files for the first time. I singled it down to 1 file:

SOAPdenovo31mer pregraph -s test_05.cfg -o test_05 -p 24

Version 1.3: released on Nov 23th, 2009

In test_05.cfg, 1 libs, max seq len 1195, max name len 256

Turns out the problem wasn't my input, but my configuration settings. The library had reverse_seq=1 for a single-read fasta file. Returning reverse_seq=0 fixed my problem...
