Comment (by gp1308):

 Updates about `leak summary` error mentioned in comment: All Valgrind
 errors are reported for backend `honey`.

 All erros are similar to the one below, I am not sure to which testcase
 this error is related, since outputs are mixed.

 I tried running only backend `honey` in a separate process (using
 `-bhoney`) that gives no error. A single process might not trigger this
