Unlikely.

I disagree.

But:

lib/xmalloc.c:    fatal("Virtual memory exhausted", EC_TEMPFAIL);

This code actually can't be reached:

     b->buf = (char*)xrealloc(b->buf, len);
     if (b->buf == NULL) {
       squat_set_last_error(SQUAT_ERR_OUT_OF_MEMORY);
       return NULL;
     }

If the xrealloc fails, the "fatal" above is called within that routine.
