跑代碼時發現有如下報錯：
LeakSanitizer: bad pointer 0x7ffd00735130
==38254==Sanitizer CHECK failed: ../../../../libsanitizer/sanitizer_common/sanitizer_allocator_secondary.h:174 ((IsAligned(reinterpret_cast<uptr>(p), page_size_))) != (0) (0, 0)
按照如上修改后，問題解決，紅框內是出問題時的編碼，原因是指針用法有問題，這里定義了一塊結構體但沒有給其分配內存
諸如類似的錯誤還有：
LeakSanitizer:DEADLYSIGNAL
==40645==ERROR: LeakSanitizer: SEGV on unknown address 0x7f97d2723000 (pc 0x7f97d10b4d0c bp0x7ffe6ff2b740 sp 0x7ffe6ff2b080 T0)

一般都是指針用法上的問題
