Problem was already reported on this list the 23 of December,
a bypass/solution was given by John Reiser.

$ grep -r __bzero valgrind-3.12
===== coregrind/m_main.c
#if defined(VGO_darwin) && DARWIN_VERS == DARWIN_10_10
/* This might also be needed for > DARWIN_10_10, but I have no way
to test for that. Hence '==' rather than '>=' in the version
test above. */
void __bzero ( void* s, UWord n );
void __bzero ( void* s, UWord n )
{
(void) VG_(memset)( s, 0, n );
}
#endif

So a timid developer chose "not functional" versus
"works, but perhaps a few microseconds slower".
Just change it to
#if defined(VGO_darwin)
omitting the test of DARWIN_VERS.
