actually it works. I saw the segmentfault function and callstacks.

But I meet breakpoints problem.

when I set break points at the code line which contain the variable defined
in origin FFmpeg such as:

    MXFContext *mxf = s->priv_data;

    put_buffer(pb, primer_pack_key, 16);

it actually stop at the correct line.

but when I set break points at the code line which contain the new variables
such as:

    local_tag_number = sizeof(mxf_local_tag_batch);
    rand_num = rand_num%256 + 1;

it can not stop at there.

It seems like, gdb didn't load the symbols of the new variables in mxfenc.c

Any ideas?
