c++ - ARM和Intel发生奇怪的崩溃

Question

仇恨者会讨厌，但由于无法将问题分开，因此我无法提供源代码，但是我将尽力提供尽可能多的信息。

所以我的问题是，在我使用的C++库(OpenCASCADE)中定义明确的位置，我的应用程序在定义明确的情况下崩溃了。

仅当我从新线程

运行代码时，才会发生崩溃

线程

之间没有共享数据

在运行方法中的第一条指令之前，崩溃发生在方法调用中。这是一个令人反感的:
Shapr3D`GeomInt_ParFunctionOfMyGradientOfTheComputeLineBezierOfWLApprox::Perform(math_Vector const&) at AppParCurves_Function.gxx:262: 0x10b5701b0: pushq %rbp 0x10b5701b1: movq %rsp, %rbp 0x10b5701b4: subq $0x663e0, %rsp 0x10b5701bb: movq %rdi, -0x8(%rbp) 0x10b5701bf: movq %rsi, -0x10(%rbp) 0x10b5701c3: movq -0x8(%rbp), %rsi 0x10b5701c7: movq %rsi, %rdi 0x10b5701ca: addq $0xc0, %rdi 0x10b5701d1: movq -0x10(%rbp), %rax 0x10b5701d5: movq %rsi, -0x65ba0(%rbp) //Crashes here 0x10b5701dc: movq %rax, %rsi 0x10b5701df: callq 0x10c050d76 ; symbol stub for: math_Vector::operator=(math_Vector const&) 0x10b5701e4: movq -0x65ba0(%rbp), %rsi 0x10b5701eb: addq $0x8828, %rsi 0x10b5701f2: movq -0x65ba0(%rbp), %rdi 0x10b5701f9: addq $0xc0, %rdi 0x10b570200: movq %rdi, -0x65ba8(%rbp) 0x10b570207: movq %rsi, %rdi 0x10b57020a: movq -0x65ba8(%rbp), %rsi 0x10b570211: movq %rax, -0x65bb0(%rbp)

由于访问错误而崩溃:EXC_BAD_ACCESS(code = 1，address = 0x9f1606100)

调用方法的对象是动态分配还是静态分配的

都没有关系

我提供了Intel的取消安装信息，但崩溃同时发生在Mac OS和iOS，32位和64位

上

Valgrind没有发现任何问题

另外，这是一个调用栈(除非您熟悉OpenCASCADE，否则它可能不会很有用)

我知道没有消息来源真的很难提供帮助，但是目前这是我所能提供的最好的服务，而且我真的很固执。我希望至少有人可以给我一些提示。我将尝试提供任何必要的信息。

该方法使用以下方法在堆栈上进行大量分配:

0x10b5701b4:  subq   $0x663e0, %rsp

使用以下方法存储到堆栈时，您的应用程序崩溃了:

0x10b5701d5:  movq   %rsi, -0x65ba0(%rbp)   //Crashes here

(它使用 RBP 作为帧指针)

因此，我怀疑堆栈溢出。尝试increasing the stack size for this thread。注意0x663e0是418784字节，这确实是要使用的大量堆栈。
