    Iris Plus OpenGL GLSL shader compile fails, but no error in the log.


      I am having trouble compiling GLSL shader programs on a NUC Mini NUC7i7BNH.  glCompileShader yields False for GL_COMPILE_STATUS but glGetShaderInfoLog returns just a single newline, no error messages.  Then sometimes glLinkProgram and glValidateProgram accept the shaders anyway, GL_LINK_STATUS and GL_VALIDATE_STATUS are both True.  But for some other shaders, glLinkProgram complains "shader not compiled", GL_LINK_STATUS is False, and eventually glGetUniformLocation posts an error, GL_INVALID_OPERATION.
