Why does block rotation affect right-click subsystem builds in Real Time Workshop 6.1 (R14SP1)?

The following error message appears in the build log when I use the "Real-Time Workshop > Build Subsystem" right-click context menu option to build a subsystem in my model:

 ### Starting Real-Time Workshop build procedure for model: RotateIWork

 ### Generating code into build directory: D:\Temp\NG\RotateIWork_ert_rtw

 Warning: Output port 1 of 'RotateIWork/' is not connected.

 Warning: Output port 1 of 'RotateIWork' is not connected.

 Error using ==> slbuild

 Error using ==> RTW.makertw.make_rtw

 Error using ==> tlc_c

 Error using ==> rtwgen

 --> Invalid setting for output port dimensions of 'RotateIWork/adadac'. The dimensions are being set to 24. This is not valid because the total number of input and output elements are not the same.

 --> Error in port widths or dimensions.  Input port 1 of 'RotateIWork/RotateIWork' is a one dimensional vector with 24 elements.

If I use "Format > Rotate Block" to rotate the subsystem block, the build completes successfully.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

In Real Time Workshop 6.1 (R14SP1), the "Real-Time Workshop > Build Subsystem" right-click context menu option contains a bug.

A possible workaround is to use the "Format -> Rotate Block" (Ctrl+R) option to rotate the subsystem block before initiating the subsystem build.
