This is probably a duplicate of PR 55978 (which, however, was claimed to be due
to r195125, which does not match the interval in comment 0).

As said in pr55978 comment #2, the bug is latent on some platforms (e.g.,
darwin) so it may not be triggered by the testsuite and may need to use
valgrind to see it. As any latent bug it may be exposed in the test suite by
unrelated changes (I still don't see it on darwin at r195432). Si I am marking
the PR as a duplicate of pr55978.
