Comment:

 The most recent valgrind release seems to be 3.11.0:

 http://valgrind.org/docs/manual/dist.news.html

 which apparently has '''preliminary''' support for OS X 10.11:

 > There is also preliminary support for X86/MacOSX 10.11, AMD64/MacOSX
 10.11 and TILEGX/Linux.

 So perhaps problems are to be expected.

 My guess is that the suppressions file probably needs to be updated for
 each OS X release - this blog post talks about needing to create your own
 for 10.10:

 I think it's worth having an open ticket for the issue that valgrind leak
 checking can give false positives on recent OS X versions - it's something
 we should at least document, and ideally workaround - e.g. by providing a
 suppressions file (if there's one in valgrind's VCS we can probably just
 use that), or by disabling leak checking automatically.
