Starting valgrind with a Closed Source OSX App like Safari or iBooks results in an ASSERT

valgrind: m_syswrap/syswrap-amd64-darwin.c:507 (void wqthread_hijack(Addr, Addr, Addr, Addr, Int, Addr)): Assertion 'tst->os_state.pthread - magic_delta == self' failed.

Starting with valgrind ls -a works as expected, so it probably an issues with too large a surface area, but valgrind ends asking me to file a bug.

Sorry if this is noise...

Comment 1 Rhys Kidd 2016-08-10 06:43:26 UTC 
This is a known issue with valgrind 3.11 and OS X 10.11.

If you update to the in-development SVN version of valgrind (3.12), rather than the homebrew packaged version, then this bug should be fixed. If you update and the bug still occurs, please re-open.

*** This bug has been marked as a duplicate of bug 354883 ***
