This is a snippet from my simple deep reader (half RGBA, float Z)- minus all the cleanup.
It was written some time ago as a simple test, but it works for the purpose. Maybe it helps you find the issue.

Imf::Array2D< unsigned int > sampleCount;
Imf::Array2D< half* > dataR, dataG, dataB, dataA;
void readDeepExr(const char *filename)
{
Imf::DeepScanLineInputFile file(filename);
const Imf::Header &header = file.header();
dataWindow = header.dataWindow();
displayWindow = header.displayWindow();
width = dataWindow.max.x - dataWindow.min.x + 1;
height = dataWindow.max.y - dataWindow.min.y + 1;
sampleCount.resizeEraseUnsafe(height, width);
Imf::Array2D< float* >dataZ(height, width);
dataR.resizeEraseUnsafe(height, width); dataG.resizeEraseUnsafe(height, width);
dataB.resizeEraseUnsafe(height, width); dataA.resizeEraseUnsafe(height, width);
Imf::DeepFrameBuffer frameBuffer;
frameBuffer.insertSampleCountSlice (Imf::Slice (Imf::UINT,
(char *) (&sampleCount[0][0] - dataWindow.min.x - dataWindow.min.y * width),
sizeof (unsigned int) * 1, // xStride
sizeof (unsigned int) * width)); // yStride
frameBuffer.insert ("Z",
Imf::DeepSlice (Imf::FLOAT, (char *) (&dataZ[0][0] - dataWindow.min.x - dataWindow.min.y * width),
sizeof (float *) * 1, // xStride for pointer array
sizeof (float *) * width, // yStride for pointer array
sizeof (float) * 1)); // stride for Z data sample

file.setFrameBuffer(frameBuffer);
file.readPixelSampleCounts(dataWindow.min.y, dataWindow.max.y);
for (int y = 0; y < height; y++)
{
for (int x = 0; x < width; x++)
{
int s = sampleCount[y][x];
dataZ[y][x] = new float[s];
dataR[y][x] = new half[s];
dataG[y][x] = new half[s];
dataB[y][x] = new half[s];
dataA[y][x] = new half[s];
}
}
file.readPixels(dataWindow.min.y, dataWindow.max.y);
std::cout << "Done.\n";
// clean up etc...
}
