HELP！ZFEC ERROR！

[.丶Ever]

Hi, recently i used zfec to do encoding and decoding. When the file size rised to 1G, it occurs some error, and i don't know how to fix it or i cannot figure out waht causes these errors.


my k=210, m=420, every block size is 1460, so for 1G file every 306600 bytes do once encoding.
Here is the error i found out:
fec.c:271: _invert_mat: Assertion `ipiv[ix] <= 1'
fec.c:289: _invert_mat: Assertion `c != 0' failed.


Can you guys tell me what's the reason and how to fix it?
Thanks for reading my letter , I am looking forward to your reply.
