Sonarcloud issues the following warning:

This "memset" is likely to be optimized away by the compiler; either remove it or replace it with "memset_s".
"memset" should not be used to delete sensitive data.

Regarding the following chunk of code:
```
void AdlChunk::chop() {
  AdlChunk *k = this;
  while( k ) {
    AdlChunk *tmp = k->_next;
    // clear out this chunk (to detect allocation bugs)
    memset(k, 0xBE, k->_len);
    free(k); // Free chunk (was malloc'd)
    k = tmp;
  }
}
```
