DTrace on Mac OS X fails due to trace events using 'self' as an argument name:
GEN trace/generated-tracers-dtrace.h dtrace: failed to compile script trace/generated-tracers-dtrace.dtrace: line 1330: syntax error, unexpected DT_KEY_SELF, expecting ) near "self" make: *** [trace/generated-tracers-dtrace.h] Error 1 Filter argument names according to the list of DTrace .d file reserved keywords. Note that DTrace on Mac and Linux still do not work after this patch. There are additional build issues remaining.
