nvcc dies with 128-bit structures

[ufimtsev]

The following code crashes nvcc5. Compile with
nvcc main.cu -Itrove-master -arch=compute_35

include <trove/ptr.h>

struct WU32
{
unsigned int data[32];
};

global void kernel(WU32* in, WU32* out)
{
int tid = blockIdx.x*blockDim.x + threadIdx.x;
trove::coalesced_ptr p(in);
WU32 r = p[tid];
trove::store_warp_contiguous(r, out+tid);
}

int main(int argc, char** argv)
{
return 0;
}

Thanks for reporting this. I have reproduced this bug under CUDA 5.0.

The good news is that my internal nvcc build does not exhibit this bug. I expect the next public CUDA release will fix it.
