It crashes in Module::genobjfile, in this call:

free(covb);

covb is allocated via:

covb = (unsigned *)calloc((numlines + 32) / 32, sizeof(*covb));

I would sure like to understand the meaning of this magical expression. Why is
it dividing by 32? Another case of premature optimization?

If you replace that with:

covb = (unsigned *)calloc(numlines, sizeof(*covb));

Then it works fine.
