Segmentation fault (core dumped)
According back trace, it crashed in linevector_free() called from
apply_rcs_changes() operating on local temporary lines structure while
dereferrencing vec->vector[ln]:
/* Free storage associated with linevector. */
static void
linevector_free (vec)
struct linevector *vec;
{
unsigned int ln;
if (vec->vector != NULL)
{
for (ln = 0; ln < vec->nlines; ++ln)
→ if (vec->vector[ln] && --vec->vector[ln]->refcount == 0)
^^^^^^^^^^^^^^^^^
free (vec->vector[ln]);
free (vec->vector);
}
}
