Repair Error

Hi. In my project, at the University, I used this library. When analyzing the code, I found an error.

File dmtxreedsol.c

Func static DmtxBoolean RsFindErrorLocatorPoly(DmtxByteList *elpOut, const DmtxByteList *syn, int errorWordCount, int maxCorrectable)

    ...
    /* Calculate error location polynomial elp[i] (set 1st term) */
    for(lambda = elp[m].length - 1, j = 0; j <= lambda; j++)
        elp[iNext].b[j+i-m] = antilog301[(NN - log301[dis.b[m]] +
        log301[dis.b[i]] + log301[elp[m].b[j]]) % NN];
    ...

There should be an additional check for 0 here My code is

    for(lambda = elp[m].length - 1, j = 0; j <= lambda; j++)
        elp[iNext].b[j+i-m] = elp[i - 1][j] == 0 ? 0 : 
            antilog301[(NN - log301[dis.b[m]] +
            log301[dis.b[i]] + log301[elp[m].b[j]]) % NN];
