Valgrind 报的 suppressed: 4 from 4 有问题吗？

RT，valgrind检查的结果如下，没有泄露以及error，但有个括弧，（suppressed: 4 from 4），这个“suppressed: 4 from 4” 代表什么意思？

==22778== HEAP SUMMARY:
==22778== in use at exit: 0 bytes in 0 blocks
==22778== total heap usage: 1 allocs, 1 frees, 40,000 bytes allocated

谢谢～

没有问题。 suppressed选项表示对某些库产生的错误不予以提示，这些错误会被统计到suppressed项目里。
