CTest Failed for Clang

There are two tests in sparse_shape.cpp file which fail for Clang Build (but works fine for GCC build)

1. At line 33
2. At line 191
   This needs to be fixed.

Output from these tests are in: /home/runner/work/TensorWrapper/TensorWrapper/build/Testing/Temporary/LastTest.log
Use "--rerun-failed --output-on-failure" to re-run the failed cases verbosely.

The following tests FAILED:
1 - test_tensorwrapper (Failed)
Error: Process completed with exit code 8.

Start with tests/tensor/shapes/sparse_shape.cpp at lines 33 and 191, then rerun the failed test with ctest --rerun-failed --output-on-failure under the Clang build and compare it with GCC. Trace the SparseMap not consistent with idx2mode failures and confirm that both SparseShape cases pass without exceptions and the full test suite succeeds.
