DSP/BIOS: Main() not entered when using both TASK and SEM

When I attempt to use a TASK and SEM in my project,  main() is not entered. I can use either TASK or SEM and the code works fine. I have been able to get the example mutex project to work but can't in my project.  Here's a portion of the .tcf file showing the ONLY changes that make this either work or not:

This works:

//bios.SEM.create("SEM0");

bios.TSK.create("TSK0");
bios.TSK.instance("TSK0").order = 2;
bios.TSK.instance("TSK0").fxn = prog.extern("task");

This works:

bios.SEM.create("SEM0");

//bios.TSK.create("TSK0");
//bios.TSK.instance("TSK0").order = 2;
//bios.TSK.instance("TSK0").fxn = prog.extern("task");

This does NOT work:

bios.SEM.create("SEM0");

bios.TSK.create("TSK0");
bios.TSK.instance("TSK0").order = 2;
bios.TSK.instance("TSK0").fxn = prog.extern("task");

Any help to resolve this would be greatly appreciated.
