ARM和英特尔的奇怪崩溃

Question

仇恨者会讨厌，但我无法提供此问题的源代码，因为我无法将问题分开，但我会尽力提供尽可能多的信息。

所以我的问题是，我的应用程序在明确定义的情况下崩溃，在我使用的 C++ 库 (OpenCASCADE) 中明确定义的点。

1. 只有在我从新线程运行代码时才会发生崩溃
2. 线程之间没有共享数据

3. 崩溃发生在方法调用中，在方法中的第一条指令运行之前。这里是一个dissassambly：

   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)

4. 它因访问错误而崩溃：EXC_BAD_ACCESS（代码=1，地址=0x9f1606100）

5. 方法调用的对象是动态分配还是静态分配都没有关系
6. 我提供的 Intel 解体，但崩溃发生在 Mac OS 和 iOS，32 位和 64 位
7. Valgrind 没有发现任何问题
8. 另外，这里有一个调用堆栈（这可能不是很有用，除非您熟悉 OpenCASCADE）

我知道如果没有来源就很难提供帮助，但目前这是我能提供的最好的，我真的被困住了。我希望至少有人能给我一些提示。我会尽力提供任何必要的信息。

Answer 1

该方法在堆栈上进行大量分配：

0x10b5701b4:  subq   $0x663e0, %rsp

并且您的应用在存储到堆栈时崩溃了：

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。试试increasing the stack size for this thread。请注意，0x663e0 是 418784 字节，这确实是一个非常大的堆栈量。
