nvopencc options? ... to avoid the crash

When I compile my code I get the following error:
nvopencc ERROR: C:\NVIDIA\CUDA\bin64/…/open64/lib//be.exe returned non-zero status -1073741571

further investigation showed
Unhandled exception at 0x004a54e8 in be.exe: 0xC00000FD: Stack overflow.

No matter how I try to transform my CUDA code, the code is either doing nothing useful or I get the crash at compilation phase.
Since it is at nvopencc stage I wondered, maybe I could pass some parameter to nvopencc via -Xopencc parameter in nvcc.
However I failed to find a list of possible options. I checked “The CUDA Compiler Driver NVCC” pdf file and google.

Or maybe this is pointless, because be.exe is some other component? If so - what is it?

The default stack size of .EXE binary files can be edited (increased) with some tools.
Google for “windows editbin”

I found it: --opencc-options="-O0"

But now compiler is much worse at detecting where given pointer is pointing to (shared or global).

If you compile the following code with -O0 it will crash or produce 123 output. With -O2 it will yeld correct 345 result.

class MyClass {

public:

	int *data;

	__device__ MyClass(int *src) {

		data=src;

	}

	__device__ int &at(int idx) {

		return data[idx];

	}

};

__global__ void func2(int *out) {

	__shared__ int arr[256];

	arr[0]=123;

	MyClass x(arr);

	x.at(0)=345;

	*out=arr[0];

}

void isolatedProblem2() {

	int *gpuPtr;

	cudaMalloc( (void**)&gpuPtr, sizeof(int));

	func2<<<1,1>>>(gpuPtr);

	int hVar;

	cudaMemcpy(&hVar,gpuPtr,sizeof(int),cudaMemcpyDeviceToHost);

	printf("%d\n",hVar);

}

I might end up modifying the stack size as you suggested, cbuchner1 - thank you.

I just wanted to try a way where I don’t have to mess up with executables…

OK, increased stack size of
\open64\lib\be.exe
from 2M to 16M and now it seems to be working. Again - many thanks for the hint!
Nevertheless I would like to express my discontent that such ugly tricks have to be done to make the compiler working!
