valgrind allocs 多于 frees 但没有泄漏

Question

我遇到了一个问题..当我用我的程序运行 valgrind 时，我得到了以下输出，这让我很困惑:

==12919== HEAP SUMMARY:
==12919==     in use at exit: 97,820 bytes in 1 blocks
==12919==   total heap usage: 17 allocs, 16 frees, 99,388 bytes allocated
==12919==
==12919== LEAK SUMMARY:
==12919==    definitely lost: 0 bytes in 0 blocks
==12919==    indirectly lost: 0 bytes in 0 blocks
==12919==      possibly lost: 0 bytes in 0 blocks
==12919==    still reachable: 97,820 bytes in 1 blocks
==12919==         suppressed: 0 bytes in 0 blocks
==12919== Reachable blocks (those to which a pointer was found) are not shown.
==12919== To see them, rerun with: --leak-check=full --show-reachable=yes
==12919==
==12919== For counts of detected and suppressed errors, rerun with: -v
==12919== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 6 from 6)

我发现它是由带有“-pg”标志的编译引起的。没有它一切都好!
