after creation of erasure code:
encoder out1.dat 9 2 cauchy_good 9 1024 500000

if you go into /coding directory and delete one of the data file (ie: out1_k1.dat)
the decode actually work fine. (as shown below)

Decoding (MB/sec): 1780.2648556876
De_Total (MB/sec): 302.0309642111

The problem is when you DO NOT delete any data file, basically decode without any missing segment
doing so, it will result in core dump

Core dump happen here, and cdf=0

for (x = 0; x < cdf; x++) {
drive = row_ids[x+ddf+k]-k;
ptr = real_decoding_matrix + k_w_w*(ddf+x);

Could you re-open this issue at http://lab.jerasure.org/jerasure/jerasure/issues ? The github site is just a convenient mirror, and not actually where the developers are working on stuff.
