Set Stack Size Test Crash

[emrainey]

Describe the bug
When building with cmake -B build -S . -DENABLE_STD_THREADS:BOOL=ON -DENABLE_REGRESSION:BOOL=ON -DENABLE_EXAMPLES:BOOL=ON the set_stack_size test has a fault.

To Reproduce
Steps to reproduce the behavior:

1. Indicate the SystemC version - 3.0.2
2. Include any relevant API calls - set_stack_size
3. Show how you run the simulation (e.g., command line, scripts). - ran unit test directly
4. Indicate where the error occurs (e.g., during elaboration, simulation, ...) - unit test

Expected behavior
I would expect no crash. If this API requires PTHREAD then this test should be disabled or "xfail" when only std::thread is used.
