To reproduce checkout the PR https://github.com/scality/quadiron/pull/266, make install and compile liberasurecode with https://github.com/scality/liberasurecode/pull/1/files and run 

$ export LD_LIBRARY_PATH=`pwd`/src/.libs:/usr/local/lib
$ valgrind test/.libs/liberasurecode_test

I found following points:

These issues raise in cases where block size is smaller than pkt_size * sizeof(T).
