Bug report: UAV toolbox uavDubinsConnection obj results in Accelerator mode reference model compilation failure when used in a Simulink MATLAB function block

Problem description:

When an uavDubinsConnection object (Dubins path connection for UAV - MATLAB (mathworks.com)) is used in a Simulink MATLAB function block (Include MATLAB code in models that generate embeddable C code - Simulink (mathworks.com)), the resulting .slx model cannot be called by a parent model through model reference (Reference another model to create model hierarchy - Simulink (mathworks.com)) in accelerator mode. The corresponding error message states:

Note that this bug is related to ARM platform binaries from C++ code generated for uavDubinsConnection - MATLAB Answers - MATLAB Central (mathworks.com).

Reproduction steps:

1. create a variable Ts = 0.1 in MATLAB base workspace.
2. run parentMdl.slx in the attachment.
