Turning on the 'Optimize using the specified minimum and maximum values' setting seems to remove critical code

Hi, I'm using Embedded Coder to generate code for my model. In the Config Params under 'Optimization', there is a setting called 'Optimize using the specified minimum and maximum values'. I observe that when this setting is off, I'm able to generate code for my model as desired. However, when this setting is turned on, I observe code corresponding to a part of a subsystem to be removed ("optimized" away) and this is undesirable. 

Is this a bug?

Please review the code that seems to be removed when the 'Optimize using the specified minimum and maximum values' setting is turned on. It is possible that the code is dead or unreachable due to maximum or minimum limits you specify for your signals or parameters. This setting tells the code generation algorithm that there are parts of the model that are unused and therefore, it is redundant to generate code for them.  For more information on this setting, please review the following documentation page:
