If Built in debug mode with msvc, output is pure black.

In contrast, build in release mode is normal.

	dst[pos] = (T)m_pucGammaLUT[clamp((int)((src[pos] - m_anAirlight[0]) / transmission + m_anAirlight[0]), 0, peak)];
	dst[pos + 1] = (T)m_pucGammaLUT[clamp((int)((src[pos + 1] - m_anAirlight[1]) / transmission + m_anAirlight[1]), 0, peak)];
	dst[pos + 2] = (T)m_pucGammaLUT[clamp((int)((src[pos + 2] - m_anAirlight[2]) / transmission + m_anAirlight[2]), 0, peak)];

Maybe it's related with above code. When debug by breakpoint, I get -2147483648, which is the minimum value for signed long type.
In release mode, some code is optimized, but in debug mode this code is stilling running and occurs error.
