-// 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.
-//
-// 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.
