Why am I unable to use Simulink Accelerator 6.0 (R14) and Simulink Accelerator 6.1 (R14SP1) on a model that has an S-function block?

I open a blank Simulink model and put the S-function Builder block in the diagram. I then used this S-function Builder block to construct and compile the S-function.

Then in my main model I used the regular S-function block with the DLL obtained from the S-function Builder block. I can run my main model in normal mode, but when I try to run it in accelerated mode, I get the following error:

 Error using ==> accelbuild_private

 Error using ==> slbuild

 Error using ==> RTW.makertw.make_rtw

 Error using ==> rtw_c

 Error(s) encountered while building model "name of the model"

This bug has been fixed in Release 2006b (R2006b). For previous product releases, read below for any possible workarounds:

We have verified that there is a bug in Simulink Accelerator 6.0 (R14) and Simulink Accelerator 6.0.1 (R14SP1) in the way that it handles .dll files obtained from the S Function Builder block.

To work around this issue, use the S-function Builder block instead of the S-function block in your main model.
