[1.36.9] WindowsError: "The system cannot find the file specified"

I was trying upgrade from precompiled 1.35.0 to 1.36.9 on Windows 10 Anniversary Update. Compilation was finished without any error but running it gives this error:

Omitting -O2 optimization option is a workaround, but I can't understand why this occurs.
