+// Most internal logging should use malloc_report() or malloc_vreport(). The
+// flags argument should be a combination of the MALLOC_REPORT_xxx values and
+// an optional log level encoded using the ASL_LEVEL_xxx constants. The log
+// level is ignored if MALLOC_REPORT_NOLOG is set.
+//
+// The flags do the following:
+//	MALLOC_REPORT_NOLOG:
+//			Does not send the text to _simple_asl_log().
+//	MALLOC_REPORT_NO_PREFIX:
+//			Does not write the program name, pid and thread identifier before
+//			the report text.
+//	MALLOC_REPORTDEBUG:
+//			includes text suggesting that a breakpoint could be set
+//			on malloc_error_break() to debug this kind of error.
+//	MALLOC_REPORT_CRASH:
+//			Same as MALLOC_REPORTDEBUG, but crashes after writing the report
+//			message.
+//	MALLOC_REPORT_BACKTRACE:
+//			Append a UUID+offset backtrace to the report text.
+//	MALLOC_REPORT_NOWRITE:
+//			Does not send the text to malloc_debug_file.
+//
+// In addition, if MALLOC_REPORT_CRASH or MALLOC_REPORTDEBUG are specified, this
+// function will sleep for an hour or send a SIGSTOP signal to the process if
+// the MallocErrorSleep and MallocErrorStop environment variables were set and
+// the report text will include a message indicating that this is
+// happening. In the case of MALLOC_REPORT_CRASH, the crash occurs after all of
+// the other actions have completed.
