Test Case

TC-MCORE-FS-1.2

Reproduction steps

The TC-MCORE-FS-1.2 test case fails due to two distinct errors:

1. An AttributeError occurs during the execution of the test_TC_MCORE_FS_1_2 method.
2. A ValueError occurs during the on_fail method execution, indicating that ctypes objects containing pointers cannot be pickled.
