本机C＆＃x2b;＆＃x2b;的内存问题在Windows上的应用
我正在研究一个bad_alloc崩溃的多线程本机CPP应用程序，从windbg中，它显然是在分配堆上的大对象时发生的（主要是basic_string ctor或与新操作员分配的一些数组分配）。从！地址-Summary和来自Debugdiag的内存分析似乎很高，但堆的大小仍然很小（约70 MB）。

我想从用法表中深入了解内存，并找出更高的内存分配的原因，有关如何进一步进行的任何建议？
I'm investigating a bad_alloc crashes for a multithreaded native cpp app, from WinDbg it's clearly happening on allocating large object on heap (mostly basic_string ctor or some array allocation with new operator). From the !address -summary and memory analysis from DebugDiag it's seems like app memory usage is very high but heap size is still very small (around 70 MB).

I want to dig deep into the memory from the usage table and find out the cause of higher memory allocation, any suggestion on how to proceed further?
